 Message (Web Content Accessibility Guidelines 1.0) [ACCESSIBILITY][73] WCAG 1.0 accessibility checking is disabled.
 Message (Section 508 Accessibility Standards) [ACCESSIBILITY][73] Section 508 accessibility checking is disabled.
2:1Warning[24] A document type declaration should normally appear as the second line for XHTML documents (the first line should be an XML declaration). For example, for XHTML 1.0 Strict documents, <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> should be the second line (or the first line if there is no XML declaration). For XHTML 1.0 Transitional documents, the line should be <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">. For XHTML 1.0 Frameset documents, the line should be <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "DTD/xhtml1-frameset.dtd">. Although the XHTML recommendation requires this line, most browsers probably ignore it. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
3:1ErrorThe "xmlns:w" attribute is not valid for the "html" element. Some valid attributes for this element are: "dir", "lang", "version", and "xmlns".

xmlns:w="urn:schemas-microsoft-com:office:word"

21:8Warning (Search Engine)[8] This document's title contains no words. This is inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
21:8Warning[108] This document has a "title" element but it does not contain a title.
21:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
56:2WarningHTML 4.01 and XHTML require the "type" attribute for the "style" element to specify the style sheet language. For example, use type="text/css". Note that many browsers may work without this attribute but it is highly recommended that it be used.
57:2WarningIn XHTML documents, style and script content must not be in a comment because it technically means that the browser will see it as a comment and not as actual style or script content (though browsers are currently forgiving about this). However, not using comments makes your document less compatible with pre HTML 3.2 browsers (but most browsers now in use are HTML 3.2+ compatible). For maximum compatibility, consider putting the style information in an external style sheet. The next best option for XHTML documents is to not put the style information in a comment because this is technically not what you want even though it may work with today's browsers.
122:12ErrorThe attribute value "IT" for the "lang" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<body lang=IT style='tab-interval:35.4pt'>
 

122:15Message (General) [CSS]The "style" attribute has been used but a default style sheet language has not been defined (note that HTML Validator would not see this declaration if it is sent as an HTTP header by a web server). HTML 4.01 and XHTML require this for correct documents. However, for all practical purposes, leaving it out is very unlikely to cause problems. If you still want to define a default style sheet language, then include this in the "head" section of your document to specify "text/css" as the default style sheet language: <meta http-equiv="Content-Style-Type" content="text/css" />. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. Because this issue is very unlikely to cause problems, consider ignoring or disabling this message. See http://www.w3.org/TR/html4/present/styles.html#default-style for more information.
122:15Message (CSS Tips) [CSS]Use the inline "style" attribute sparingly. Using this attribute too often can prevent you from receiving many of the benefits of CSS like easier to maintain and less cluttered documents. Consider using a single CSS style sheet instead of relying too much on the "style" attribute. This message is displayed only once.
124:20Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
124:4Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="center", consider using the CSS "text-align: center" instead.
124:20Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility. For these reasons and others, it is highly recommended that appropriate alt text be specified using the "alt" attribute. This message is displayed only once.
125:12ErrorThe attribute value "Section1" for the "class" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<div class=Section1>
 

127:10ErrorThe attribute value "MsoNormal" for the "class" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<p class=MsoNormal><o:p><span class="Stile2"><font face="Verdana, Arial, Helvetica, sans-serif">Collezioni Litomineralogiche - marmi antichi</font></span></o:p></p>
 

127:47Message (Deprecated)[9] The "font" element and all of its attributes are deprecated in HTML 4.01 and XHTML in favor of using style sheets (use the "color", "font", "font-family", "font-size", and other CSS font properties instead).
129:10ErrorThe attribute value "2" for the "size" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<hr size=2 width="100%" align=center>
 

129:31ErrorThe attribute value "center" for the "align" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<hr size=2 width="100%" align=center>
 

129:5Message (Deprecated)[9] The "align", "noshade", "size", and "width" attributes for the "hr" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Consider using the "width" CSS property in place of the "width" attribute.
130:2Error"BR" contains uppercase characters. All start tags, end tags, and tag attributes must be in lowercase because this is an XHTML document.

<BR><img width=178 height=267
 

130:6Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
130:16ErrorThe attribute value "178" for the "width" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<BR><img width=178 height=267
 

130:27ErrorThe attribute value "267" for the "height" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<BR><img width=178 height=267
 

131:27ErrorThe "v:shapes" attribute is not valid for the "img" element. Some valid attributes for this element are: "align", "alt", "border", "class", "dir", "height", "hspace", "id", "ismap", "lang", "longdesc", "name", "onabort", "onblur", "onclick", "oncontextmenu", "ondblclick", "onerror", "onfilterchange", "onfocus", "onkeydown", "onkeypress", "onkeyup", "onload", "onmousedown", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onresize", "src", "style", "title", "usemap", "vspace", and "width".

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou can disable all the error messages for improperly quoted attribute values by having HTML Validator ignore and disregard the quotation mark requirements for attribute values. This option is in CSE HTML Validator's Validator Engine Options. However, it is recommended that you leave these error messages enabled and that you properly enclose attribute values in quotation marks.
 CommentYou can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
 CommentYou may want to turn off 128-159 character checking if you're sure that these characters will be interpreted and displayed properly by the visiting user agents. This option is in CSE HTML Validator's Validator Engine Options.

 CommentXHTML document detected.
 Comment[24] The XHTML recommendation strongly encourages that an XML declaration be used as the first line (line 1) of every XHTML document. For example, for XHTML and WML documents, something similar to <?xml version="1.0" encoding="UTF-8"?> or simply <?xml version="1.0"?> should be the first line. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. However, in practice, correctly using an XML declaration may cause problems, such as triggering Internet Explorer 6's "quirks" mode (which causes non-standards compliant rendering). Because of this, consider not using an XML declaration.

2:1Warning[24] A document type declaration should normally appear as the second line for XHTML documents (the first line should be an XML declaration). For example, for XHTML 1.0 Strict documents, <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> should be the second line (or the first line if there is no XML declaration). For XHTML 1.0 Transitional documents, the line should be <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">. For XHTML 1.0 Frameset documents, the line should be <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "DTD/xhtml1-frameset.dtd">. Although the XHTML recommendation requires this line, most browsers probably ignore it.

21:8Warning (Search Engine)[8] This document's title contains no words. This is inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
21:8Warning[108] This document has a "title" element but it does not contain a title.
21:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
56:2WarningHTML 4.01 and XHTML require the "type" attribute for the "style" element to specify the style sheet language. For example, use type="text/css". Note that many browsers may work without this attribute but it is highly recommended that it be used.
57:2WarningIn XHTML documents, style and script content must not be in a comment because it technically means that the browser will see it as a comment and not as actual style or script content (though browsers are currently forgiving about this). However, not using comments makes your document less compatible with pre HTML 3.2 browsers (but most browsers now in use are HTML 3.2+ compatible). For maximum compatibility, consider putting the style information in an external style sheet. The next best option for XHTML documents is to not put the style information in a comment because this is technically not what you want even though it may work with today's browsers.
122:12ErrorThe attribute value "IT" for the "lang" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

122:15Message (General) [CSS]The "style" attribute has been used but a default style sheet language has not been defined (note that HTML Validator would not see this declaration if it is sent as an HTTP header by a web server). HTML 4.01 and XHTML require this for correct documents. However, for all practical purposes, leaving it out is very unlikely to cause problems. If you still want to define a default style sheet language, then include this in the "head" section of your document to specify "text/css" as the default style sheet language: <meta http-equiv="Content-Style-Type" content="text/css" />. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. Because this issue is very unlikely to cause problems, consider ignoring or disabling this message. See http://www.w3.org/TR/html4/present/styles.html#default-style for more information.
122:15Message (CSS Tips) [CSS]Use the inline "style" attribute sparingly. Using this attribute too often can prevent you from receiving many of the benefits of CSS like easier to maintain and less cluttered documents. Consider using a single CSS style sheet instead of relying too much on the "style" attribute. This message is displayed only once.
124:20Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
124:4Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="center", consider using the CSS "text-align: center" instead.
124:20Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility. For these reasons and others, it is highly recommended that appropriate alt text be specified using the "alt" attribute. This message is displayed only once.
125:12ErrorThe attribute value "Section1" for the "class" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted.

129:10ErrorThe attribute value "2" for the "size" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

129:5Message (Deprecated)[9] The "align", "noshade", "size", and "width" attributes for the "hr" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Consider using the "width" CSS property in place of the "width" attribute.
130:2Error"BR" contains uppercase characters. All start tags, end tags, and tag attributes must be in lowercase because this is an XHTML document.

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou can disable all the error messages for improperly quoted attribute values by having HTML Validator ignore and disregard the quotation mark requirements for attribute values. This option is in CSE HTML Validator's Validator Engine Options. However, it is recommended that you leave these error messages enabled and that you properly enclose attribute values in quotation marks.
 CommentYou can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
 CommentYou may want to turn off 128-159 character checking if you're sure that these characters will be interpreted and displayed properly by the visiting user agents. This option is in CSE HTML Validator's Validator Engine Options.
 CommentPossibly misspelled words (68, 35 unique): antichi (1x), antico (1x), ApplyBreakingRules (1x), BreakWrappedTables (1x), colband (1x), Collezioni (1x), Litomineralogiche (1x), Litotipo (1x), marmi (1x), normale (1x), noshow (1x), rowband (1x), SnapToGridInCell (1x), Tabella (1x), table.MsoNormalTable (1x), UseAsianBreakRules (1x), UseFELayout (1x), WrapTextWithPunct (1x), BrowserLevel (2x), CharactersWithSpaces (2x), DocumentProperties (2x), Gianco (2x), GrammarState (2x), HyphenationZone (2x), LastAuthor (2x), LastSaved (2x), para (2x), SpellingState (2x), TotalTime (2x), tstyle (2x), WordDocument (2x), gte (3x), endif (4x), VML (4x), mso (13x). NOTE: Validation terminated so not all words were checked.
 CommentYou can change the maximum number of error messages to display before the validation is terminated. This option is in CSE HTML Validator's Validator Engine Options.
 CommentXHTML document detected.
 Comment[24] The XHTML recommendation strongly encourages that an XML declaration be used as the first line (line 1) of every XHTML document. For example, for XHTML and WML documents, something similar to <?xml version="1.0" encoding="UTF-8"?> or simply <?xml version="1.0"?> should be the first line. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. However, in practice, correctly using an XML declaration may cause problems, such as triggering Internet Explorer 6's "quirks" mode (which causes non-standards compliant rendering). Because of this, consider not using an XML declaration.
 Comment (Search Engine)[113] Random Search Engine Tip #18 - Look at your site's referral logs to see what keywords people are using to find your site. Use this information to improve your site. For example, you may want to add content related to keywords that have been overlooked.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)" /> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.

If you still want to define a default style sheet language, then include this in the "head" section of your document to specify "text/css" as the default style sheet language: <meta http-equiv="Content-Style-Type" content="text/css" />. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. Because this issue is very unlikely to cause problems, consider ignoring or disabling this message. See http://www.w3.org/TR/html4/present/styles.html#default-style for more information.
122:15Message (CSS Tips) [CSS]Use the inline "style" attribute sparingly. Using this attribute too often can prevent you from receiving many of the benefits of CSS like easier to maintain and less cluttered documents. Consider using a single CSS style sheet instead of relying too much on the "style" attribute. This message is displayed only once.
124:20Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
124:4Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="center", consider using the CSS "text-align: center" instead.
124:20Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility.

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou can disable all the error messages for improperly quoted attribute values by having HTML Validator ignore and disregard the quotation mark requirements for attribute values. This option is in CSE HTML Validator's Validator Engine Options. However, it is recommended that you leave these error messages enabled and that you properly enclose attribute values in quotation marks.
 CommentYou can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
 CommentYou may want to turn off 128-159 character checking if you're sure that these characters will be interpreted and displayed properly by the visiting user agents. This option is in CSE HTML Validator's Validator Engine Options.

 CommentXHTML document detected.
 Comment[24] The XHTML recommendation strongly encourages that an XML declaration be used as the first line (line 1) of every XHTML document. For example, for XHTML and WML documents, something similar to <?xml version="1.0" encoding="UTF-8"?> or simply <?xml version="1.0"?> should be the first line. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. However, in practice, correctly using an XML declaration may cause problems, such as triggering Internet Explorer 6's "quirks" mode (which causes non-standards compliant rendering). Because of this, consider not using an XML declaration.
 Comment (Search Engine)[113] Random Search Engine Tip #18 - Look at your site's referral logs to see what keywords people are using to find your site. Use this information to improve your site. For example, you may want to add content related to keywords that have been overlooked.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)" /> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 Comment (Search Engine)[8] <meta name="keywords" content="(actual keyword list)" /> should be used in the "head" section to provide a list of keywords that are relevent to this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 CommentAn ICRA RDF label was not found in the "head" section of this document. Browsers that are enabled with this rating system may not display documents that have not been labelled. It is recommended that every page include an ICRA label. For more information, please visit http://www.icra.org/.
 Comment[10] CSE HTML Validator Std/Pro allows you to disable certain messages (like this example message) and groups of related messages by disabling flags. For instance, the [10] at the beginning of this message indicates that you can disable this message by disabling validator flag 10. If you are using HTML Validator's integrated editor, then you can simply use your mouse on this message to open the context menu (usually done by right-clicking the mouse on this message) and select 'Disable Flag 10' to disable this message.

2:1Warning[24] A document type declaration should normally appear as the second line for XHTML documents (the first line should be an XML declaration). For example, for XHTML 1.0 Strict documents, <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> should be the second line (or the first line if there is no XML declaration). For XHTML 1.0 Transitional documents, the line should be <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">. For XHTML 1.0 Frameset documents, the line should be <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "DTD/xhtml1-frameset.dtd">. Although the XHTML recommendation requires this line, most browsers probably ignore it. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.

21:8Warning (Search Engine)[8] This document's title contains no words. This is inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
21:8Warning[108] This document has a "title" element but it does not contain a title.
21:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
56:2WarningHTML 4.01 and XHTML require the "type" attribute for the "style" element to specify the style sheet language. For example, use type="text/css". Note that many browsers may work without this attribute but it is highly recommended that it be used.
57:2WarningIn XHTML documents, style and script content must not be in a comment because it technically means that the browser will see it as a comment and not as actual style or script content (though browsers are currently forgiving about this). However, not using comments makes your document less compatible with pre HTML 3.2 browsers (but most browsers now in use are HTML 3.2+ compatible). For maximum compatibility, consider putting the style information in an external style sheet. The next best option for XHTML documents is to not put the style information in a comment because this is technically not what you want even though it may work with today's browsers.

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou can disable all the error messages for improperly quoted attribute values by having HTML Validator ignore and disregard the quotation mark requirements for attribute values. This option is in CSE HTML Validator's Validator Engine Options. However, it is recommended that you leave these error messages enabled and that you properly enclose attribute values in quotation marks.

2:1Warning[24] A document type declaration should normally appear as the second line for XHTML documents (the first line should be an XML declaration). For example, for XHTML 1.0 Strict documents, <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> should be the second line (or the first line if there is no XML declaration). For XHTML 1.0 Transitional documents, the line should be <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">. For XHTML 1.0 Frameset documents, the line should be <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "DTD/xhtml1-frameset.dtd">. Although the XHTML recommendation requires this line, most browsers probably ignore it. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.

21:8Warning (Search Engine)[8] This document's title contains no words. This is inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
21:8Warning[108] This document has a "title" element but it does not contain a title.
21:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
56:2WarningHTML 4.01 and XHTML require the "type" attribute for the "style" element to specify the style sheet language. For example, use type="text/css". Note that many browsers may work without this attribute but it is highly recommended that it be used.
57:2WarningIn XHTML documents, style and script content must not be in a comment because it technically means that the browser will see it as a comment and not as actual style or script content (though browsers are currently forgiving about this). However, not using comments makes your document less compatible with pre HTML 3.2 browsers (but most browsers now in use are HTML 3.2+ compatible). For maximum compatibility, consider putting the style information in an external style sheet. The next best option for XHTML documents is to not put the style information in a comment because this is technically not what you want even though it may work with today's browsers.
122:12ErrorThe attribute value "IT" for the "lang" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<body lang=IT style='tab-interval:35.4pt'>
 

122:15Message (General) [CSS]The "style" attribute has been used but a default style sheet language has not been defined (note that HTML Validator would not see this declaration if it is sent as an HTTP header by a web server). HTML 4.01 and XHTML require this for correct documents. However, for all practical purposes, leaving it out is very unlikely to cause problems. If you still want to define a default style sheet language, then include this in the "head" section of your document to specify "text/css" as the default style sheet language: <meta http-equiv="Content-Style-Type" content="text/css" />. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. Because this issue is very unlikely to cause problems, consider ignoring or disabling this message. See http://www.w3.org/TR/html4/present/styles.html#default-style for more information.
122:15Message (CSS Tips) [CSS]Use the inline "style" attribute sparingly. Using this attribute too often can prevent you from receiving many of the benefits of CSS like easier to maintain and less cluttered documents. Consider using a single CSS style sheet instead of relying too much on the "style" attribute. This message is displayed only once.
124:20Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
124:4Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="center", consider using the CSS "text-align: center" instead.
124:20Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility. For these reasons and others, it is highly recommended that appropriate alt text be specified using the "alt" attribute. This message is displayed only once.
125:12ErrorThe attribute value "Section1" for the "class" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<div class=Section1>
 

127:10ErrorThe attribute value "MsoNormal" for the "class" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<p class=MsoNormal><o:p><span class="Stile2"><font face="Verdana, Arial, Helvetica, sans-serif">Collezioni Litomineralogiche - marmi antichi</font></span></o:p></p>
 

127:47Message (Deprecated)[9] The "font" element and all of its attributes are deprecated in HTML 4.01 and XHTML in favor of using style sheets (use the "color", "font", "font-family", "font-size", and other CSS font properties instead).
129:10ErrorThe attribute value "2" for the "size" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<hr size=2 width="100%" align=center>
 

129:31ErrorThe attribute value "center" for the "align" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<hr size=2 width="100%" align=center>
 

129:5Message (Deprecated)[9] The "align", "noshade", "size", and "width" attributes for the "hr" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Consider using the "width" CSS property in place of the "width" attribute.
130:2Error"BR" contains uppercase characters. All start tags, end tags, and tag attributes must be in lowercase because this is an XHTML document.

<BR><img width=178 height=267
 

130:6Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).

22:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
22:8Message (Search Engine)[8] This document's title contains only 2 words. It may be inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
47:2WarningHTML 4.01 and XHTML require the "type" attribute for the "style" element to specify the style sheet language. For example, use type="text/css". Note that many browsers may work without this attribute but it is highly recommended that it be used.
48:2WarningIn XHTML documents, style and script content must not be in a comment because it technically means that the browser will see it as a comment and not as actual style or script content (though browsers are currently forgiving about this). However, not using comments makes your document less compatible with pre HTML 3.2 browsers (but most browsers now in use are HTML 3.2+ compatible). For maximum compatibility, consider putting the style information in an external style sheet. The next best option for XHTML documents is to not put the style information in a comment because this is technically not what you want even though it may work with today's browsers.

Quotes are recommended even if they are not required.

<body lang=IT style='tab-interval:35.4pt'>
 

136:15Message (General) [CSS]The "style" attribute has been used but a default style sheet language has not been defined (note that HTML Validator would not see this declaration if it is sent as an HTTP header by a web server). HTML 4.01 and XHTML require this for correct documents. However, for all practical purposes, leaving it out is very unlikely to cause problems. If you still want to define a default style sheet language, then include this in the "head" section of your document to specify "text/css" as the default style sheet language: <meta http-equiv="Content-Style-Type" content="text/css" />. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. Because this issue is very unlikely to cause problems, consider ignoring or disabling this message. See http://www.w3.org/TR/html4/present/styles.html#default-style for more information.
136:15Message (CSS Tips) [CSS]Use the inline "style" attribute sparingly. Using this attribute too often can prevent you from receiving many of the benefits of CSS like easier to maintain and less cluttered documents. Consider using a single CSS style sheet instead of relying too much on the "style" attribute. This message is displayed only once.
138:12ErrorThe attribute value "Section1" for the "class" attribute was not enclosed in single or double quotation marks when it must be.

141ErrorThis line contains part of a quoted string that spans more than one line (not recommended) or a quoted string (like an attribute value) that is missing the start or end quotation mark. Check this line for improperly quoted attribute values that may be missing a start or end quotation mark. As currently configured, HTML Validator requires that all quoted strings be contained on one line and have start and end quotation marks. Note that because of inconsistent handling by user agents, it is not recommended that attribute values contain line breaks.

<table border=0 cellspacing=0 cellpadding=0 style='border-collapse:collapse;
 

141:2Message (Good Style)Consider using the "width" attribute with the "table" element. This is considered to be good style and can cause the table and page to render faster. Note that this is not a deprecated attribute in HTML 4.01 nor XHTML 1.0. It's also a valid XHTML 1.1 attribute.
141:2Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.

145:112Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
145:122ErrorThe attribute value "229" for the "width" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.

<td valign=top style='width:657.0pt;padding:0cm 3.5pt 0cm 3.5pt'><p align="center"><span class="MsoNormal"><img width=229 height=342
 

145:72Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="center", consider using the CSS "text-align: center" instead.
145:112Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility. For these reasons and others, it is highly recommended that appropriate alt text be specified using the "alt" attribute. This message is displayed only once.

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou can disable all the error messages for improperly quoted attribute values by having HTML Validator ignore and disregard the quotation mark requirements for attribute values. This option is in CSE HTML Validator's Validator Engine Options. However, it is recommended that you leave these error messages enabled and that you properly enclose attribute values in quotation marks.
 CommentYou can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
 CommentYou can allow a quoted string to exist on more than one line by turning on the option to allow multi-line quotes. However, allowing multi-line quotes may make it more difficult to find problems caused by incorrect quoting. This option is in CSE HTML Validator's Validator Engine Options.
 CommentYou may want to turn off 128-159 character checking if you're sure that these characters will be interpreted and displayed properly by the visiting user agents. This option is in CSE HTML Validator's Validator Engine Options.
 CommentPossibly misspelled words (30, 14 unique): Fulloni (1x), Quintino (1x), CharactersWithSpaces (2x), DocumentProperties (2x), gte (2x), HyphenationZone (2x), LastAuthor (2x), LastPrinted (2x), LastSaved (2x), TotalTime (2x), WordDocument (2x), endif (3x), mso (3x), VML (4x). NOTE: Validation terminated so not all words were checked.

 Comment[24] The XHTML recommendation strongly encourages that an XML declaration be used as the first line (line 1) of every XHTML document. For example, for XHTML and WML documents, something similar to <?xml version="1.0" encoding="UTF-8"?> or simply <?xml version="1.0"?> should be the first line. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. However, in practice, correctly using an XML declaration may cause problems, such as triggering Internet Explorer 6's "quirks" mode (which causes non-standards compliant rendering). Because of this, consider not using an XML declaration.
 Comment (Search Engine)[113] Random Search Engine Tip #18 - Look at your site's referral logs to see what keywords people are using to find your site. Use this information to improve your site. For example, you may want to add content related to keywords that have been overlooked.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)" /> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 Comment (Search Engine)[8] <meta name="keywords" content="(actual keyword list)" /> should be used in the "head" section to provide a list of keywords that are relevent to this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 CommentAn ICRA RDF label was not found in the "head" section of this document. Browsers that are enabled with this rating system may not display documents that have not been labelled. It is recommended that every page include an ICRA label. For more information, please visit http://www.icra.org/.

1:1Warning[24] A document type declaration should appear as the first line (line 1) of every HTML document. For example, for HTML 4.01 Strict documents, <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> should be the first line. For HTML 4.01 Transitional documents, the first line should be <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">. For HTML 4.01 Frameset documents, the first line should be <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">. Although HTML recommendations generally require this line, most browsers probably ignore it. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
3:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
7:7Message (Deprecated)[9] The "background", "bgcolor", "text", "link", "vlink", and "alink" attributes for the "body" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of the "bgcolor" attribute, consider using the CSS property "background-color". Example: style="background-color: #FFFFFF". Instead of the "text" attribute, consider using the CSS property "color". Example: style="color: #000000".
8:4Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="center", consider using the CSS "text-align: center" instead.
8:20Message (Deprecated)[9] The "font" element and all of its attributes are deprecated in HTML 4.01 and XHTML in favor of using style sheets (use the "color", "font", "font-family", "font-size", and other CSS font properties instead).
8:80Message (Good Style)The "strong" element should be used instead of the "b" element when you want to denote strong emphasis. The "b" element should only be used when you want bold typeface but do not want strong emphasis. Many web authors use the "b" element when the "strong" element would be more appropriate.
14:44Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "IMG" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
14:44Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility. For these reasons and others, it is highly recommended that appropriate alt text be specified using the "alt" attribute. This message is displayed only once.

The "B" element should only be used when you want bold typeface but do not want strong emphasis. Many web authors use the "B" element when the "strong" element would be more appropriate.
17:37Message (General) [CSS]The "style" attribute has been used but a default style sheet language has not been defined (note that HTML Validator would not see this declaration if it is sent as an HTTP header by a web server). HTML 4.01 and XHTML require this for correct documents. However, for all practical purposes, leaving it out is very unlikely to cause problems. If you still want to define a default style sheet language, then include this in the "head" section of your document to specify "text/css" as the default style sheet language: <meta http-equiv="Content-Style-Type" content="text/css">. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. Because this issue is very unlikely to cause problems, consider ignoring or disabling this message. See http://www.w3.org/TR/html4/present/styles.html#default-style for more information.
17:37Message (CSS Tips) [CSS]Use the inline "STYLE" attribute sparingly. Using this attribute too often can prevent you from receiving many of the benefits of CSS like easier to maintain and less cluttered documents. Consider using a single CSS style sheet instead of relying too much on the "STYLE" attribute. This message is displayed only once.
18:5Message (Deprecated)[9] The "align", "noshade", "size", and "width" attributes for the "HR" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Consider using the "width" CSS property in place of the "width" attribute.
19:57Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "IMG" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed.

Line:charTypeMessage Description
 Message (Web Content Accessibility Guidelines 1.0) [ACCESSIBILITY][73] WCAG 1.0 accessibility checking is disabled.
 Message (Section 508 Accessibility Standards) [ACCESSIBILITY][73] Section 508 accessibility checking is disabled.
1:1Warning[24] A document type declaration should appear as the first line (line 1) of every HTML document. For example, for HTML 4.01 Strict documents, <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> should be the first line. For HTML 4.01 Transitional documents, the first line should be <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">. For HTML 4.01 Frameset documents, the first line should be <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">. Although HTML recommendations generally require this line, most browsers probably ignore it. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
3:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
3:8Message (Search Engine)[8] This document's title contains only 4 words. It may be inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
7:7Message (Deprecated)[9] The "background", "bgcolor", "text", "link", "vlink", and "alink" attributes for the "body" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of the "bgcolor" attribute, consider using the CSS property "background-color". Example: style="background-color: #FFFFFF". Instead of the "text" attribute, consider using the CSS property "color". Example: style="color: #000000".
8:6Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="center", consider using the CSS "text-align: center" instead.
9:7Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility. It lets authors specify equivalent text to serve as content when the image cannot be seen or displayed. Use alt="" when alternate text is not appropriate, such as when images are intended to format a page (such as spacer images).
9:7Message (Search Engine)[8] Alt text is often used by search engines. Use this to your advantage (but do it appropriately). Furthermore, alt text is critical for accessibility. For these reasons and others, it is highly recommended that appropriate alt text be specified using the "alt" attribute. This message is displayed only once.
10:19Message (General) [CSS]The "style" attribute has been used but a default style sheet language has not been defined (note that HTML Validator would not see this declaration if it is sent as an HTTP header by a web server). HTML 4.01 and XHTML require this for correct documents. However, for all practical purposes, leaving it out is very unlikely to cause problems. If you still want to define a default style sheet language, then include this in the "head" section of your document to specify "text/css" as the default style sheet language: <meta http-equiv="Content-Style-Type" content="text/css">. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. Because this issue is very unlikely to cause problems, consider ignoring or disabling this message. See http://www.w3.org/TR/html4/present/styles.html#default-style for more information.
10:19Message (CSS Tips) [CSS]Use the inline "style" attribute sparingly. Using this attribute too often can prevent you from receiving many of the benefits of CSS like easier to maintain and less cluttered documents. Consider using a single CSS style sheet instead of relying too much on the "style" attribute. This message is displayed only once.
10:46Message (Deprecated)[9] The "font" element and all of its attributes are deprecated in HTML 4.01 and XHTML in favor of using style sheets (use the "color", "font", "font-family", "font-size", and other CSS font properties instead).
11:8Message (Good Style)The "em" element (for emphasized text) or the "cite" element (for citations) may be more appropriate than the "i" element. Use the "i" element only if text is in italics by convention. Many web authors use the "i" element when the "em" element would be more appropriate.
 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
