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.

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.
27:20WarningThe "font" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
27:80Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "img" element. The "alt" attribute is critical for accessibility.

32:2Message (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.
32:63Message (Deprecated)[9] The "align" and "bgcolor" attributes for the "table" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="center", consider using the following CSS to center the table: "margin-left: auto; margin-right: auto". This is the correct CSS way but it may not work with some (mostly older) browsers.

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.
11:97Warning[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).
11:97Message (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.
15:2Message (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.

9:29Error (General) [CSS]The "text-underline" property is not a recognized style property. Is it misspelled?

style='text-decoration:none;text-underline:none'><img border=0 width=427
 

9:51Warning[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).
9:1Message (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.
9:1Message (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.
9:51Message (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.
10:16WarningAn "id" attribute value should not begin with an underscore character, even though this may work in most browsers. Disable this message if you want to allow these values to begin with underscore characters. Disabling this message may be helpful for ASP.NET generated pages which often incorrectly start these values with underscores.
11:20Message (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).
12:7Message (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.

8:23Message (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).
8:74Message (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.
9:5WarningAn "id" attribute value should not begin with an underscore character, even though this may work in most browsers. Disable this message if you want to allow these values to begin with underscore characters. Disabling this message may be helpful for ASP.NET generated pages which often incorrectly start these values with underscores.
11:11Message (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.
11:57Message (Good Style)[7] Underlining text may confuse your visitors because most browsers use underlining to emphasize hyperlinks.
11:57Message (Deprecated)[9] The "u" element is deprecated in HTML 4.01 and XHTML in favor of using style sheets ("text-decoration: underline").
 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.

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 3 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.
45:2WarningHTML 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.
46:2WarningIn 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.
49:3Message (General) [CSS]Found the Microsoft Office property "mso-style-parent". HTML Validator ignores these proprietary properties that begin with "mso-". This message is displayed only once. There may be other proprietary properties.
51:2Warning (General) [CSS]The "margin" shorthand property and the "margin-bottom" property have both been used. The "margin" shorthand property already defines the following properties: "margin-bottom", "margin-left", "margin-right", and "margin-top". Therefore, the "margin-bottom" property has been defined twice. Consider using only the "margin" shorthand property.
54:15Warning (General) [CSS]It is recommended that a generic font family name be specified as the last font family name. If the preceding font family names are not available then the browser should fall back to the generic font family name. The generic font family names are serif, sans-serif, cursive, fantasy, and monospace. Be sure not to use quotes around generic font family names.
58:15Warning (General) [CSS]It is recommended that a generic font family name be specified as the last font family name.

Quotes are recommended even if they are not required.

79:36Error (General) [CSS]The "tab-interval" property is not a recognized style property. Is it misspelled?

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

79:7Message (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: white".
79:29Message (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.
79:29Message (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.
80:12ErrorThe 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>
 

81:22Warning[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).
81:6Message (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.
81:22Message (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.

82:9Message (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).

 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.
 CommentPossibly misspelled words (62, 35 unique): apat (1x), aperta (1x), cervo (1x), clima (1x), Collezione (1x), Cranio (1x), di (1x), foresta (1x), freddo (1x), grosso (1x), idmap (1x), Lazio (1x), Lunghezza (1x), Provenienza (1x), shapedefaults (1x), spidmax (1x), un (1x), vertebrati (1x), Blumenbach (2x), CharactersWithSpaces (2x), DocumentProperties (2x), giganteus (2x), HyphenationZone (2x), LastAuthor (2x), LastSaved (2x), Megaceros (2x), shapelayout (2x), suo (2x), temperato (2x), TotalTime (2x), WordDocument (2x), gte (4x), VML (4x), endif (5x), mso (5x). 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.
 CommentIt is recommended that you update this HTML 4.0 document to HTML 4.01 or to XHTML. Updating to HTML 4.01 can easily be done in most cases by simply replacing the HTML 4.0 DOCTYPE with an HTML 4.01 DOCTYPE. Updating to XHTML usually requires much more work than simply changing the DOCTYPE. HTML 4.01 DOCTYPEs and other DOCTYPEs can be inserted from the Tag Inserter.
 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.

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.
45:2WarningHTML 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.
46:2WarningIn 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.
49:3Message (General) [CSS]Found the Microsoft Office property "mso-style-parent". HTML Validator ignores these proprietary properties that begin with "mso-". This message is displayed only once. There may be other proprietary properties.
51:2Warning (General) [CSS]The "margin" shorthand property and the "margin-bottom" property have both been used. The "margin" shorthand property already defines the following properties: "margin-bottom", "margin-left", "margin-right", and "margin-top". Therefore, the "margin-bottom" property has been defined twice. Consider using only the "margin" shorthand property.
54:15Warning (General) [CSS]It is recommended that a generic font family name be specified as the last font family name. If the preceding font family names are not available then the browser should fall back to the generic font family name. The generic font family names are serif, sans-serif, cursive, fantasy, and monospace. Be sure not to use quotes around generic font family names.
57:3Message (General Compatibility) [CSS][603] The "size" CSS property is an official CSS2 (but not CSS1) property and is not supported by Internet Explorer and Netscape. This includes Internet Explorer 6.0- and Netscape 6.2-.
59:2Error (General) [CSS]The "mso-header-margin" property is not a recognized style property for @page blocks. Is it misspelled?

mso-header-margin:35.4pt;
 

60:2Error (General) [CSS]The "mso-footer-margin" property is not a recognized style property for @page blocks. Is it misspelled?

mso-footer-margin:35.4pt;
 

61:2Error (General) [CSS]The "mso-paper-source" property is not a recognized style property for @page blocks. Is it misspelled?

mso-paper-source:0;}
 

63:3Message (General Compatibility) [CSS][603] The "page" CSS property is an official CSS2 (but not CSS1) property but is not currently supported by Internet Explorer, Netscape, and Opera. This includes Internet Explorer 6.0-, Netscape 6.2-, and Opera 6.0-.
72:12ErrorThe attribute value "Author" for the "name" 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.

<meta name=Author content="Francesco Angelelli">
 

75:15ErrorThe attribute value "white" for the "bgcolor" 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.

75:26ErrorThe attribute value "IT" for the "lang" attribute was not enclosed in single or double quotation marks when it must be.

75:36Error (General) [CSS]The "tab-interval" property is not a recognized style property. Is it misspelled?

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

75:7Message (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: white".
75:29Message (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.
75:29Message (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.
76:12ErrorThe 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>
 

77:12ErrorThe 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 align="center"><img width=405 height=299 id="_x0000_i1025"
 

77:38Warning[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).
77:48ErrorThe attribute value "405" 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.

<p class=MsoNormal align="center"><img width=405 height=299 id="_x0000_i1025"
 

77:59ErrorThe attribute value "299" 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.

<p class=MsoNormal align="center"><img width=405 height=299 id="_x0000_i1025"
 

77:67WarningAn "id" attribute value should not begin with an underscore character, even though this may work in most browsers. Disable this message if you want to allow these values to begin with underscore characters. Disabling this message may be helpful for ASP.NET generated pages which often incorrectly start these values with underscores.
77:22Message (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.
77:38Message (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.
78:5ErrorThe attribute value "clypeaster4.jpg" for the "src" 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.

src=clypeaster4.jpg><br>
 

79:6Message (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.
79:9Message (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).

 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.
 CommentPossibly misspelled words (61, 32 unique): anni (1x), apat (1x), Belcastro (1x), Calabria (1x), Classico (1x), Collezione (1x), di (1x), Diametro (1x), echinide (1x), idmap (1x), irregolare (1x), milioni (1x), Provenienza (1x), shapedefaults (1x), spidmax (1x), CharactersWithSpaces (2x), cipollae (2x), Clypeaster (2x), DocumentProperties (2x), HyphenationZone (2x), LastAuthor (2x), LastSaved (2x), shapelayout (2x), suo (2x), TotalTime (2x), WordDocument (2x), Checchia (3x), Rispoli (3x), gte (4x), VML (4x), endif (5x), mso (5x). 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.
 CommentIt is recommended that you update this HTML 4.0 document to HTML 4.01 or to XHTML. Updating to HTML 4.01 can easily be done in most cases by simply replacing the HTML 4.0 DOCTYPE with an HTML 4.01 DOCTYPE. Updating to XHTML usually requires much more work than simply changing the DOCTYPE. HTML 4.01 DOCTYPEs and other DOCTYPEs can be inserted from the Tag Inserter.
 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.
