Line:char | Type | Message 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.
5:2 | Message (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.
5:8 | Message (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.
49:2 | Message (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.
52:35 | Message (General Compatibility) | [5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
121:3 | Message (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.
123:8 | Message (Deprecated) | [9] The "height" and "width" attributes for the "td" and "th" elements are deprecated in HTML 4.01 and XHTML in favor of using style sheets.
133:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
155:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
173:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
204:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
227:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
232:30 | Warning | At least one character (codepoint) between 128 and 159 (inclusive) was found on line 232. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. If you are wanting the euro sign, then it is recommended that the character reference "&#8364;" be used. Another option would be to use the entity reference "&euro;".
244:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
266:14 | Message (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.
272:57 | Warning (General Compatibility) | The "bordercolor", "bordercolordark", "bordercolorlight", "frame", or "rules" attribute has been used. In order for any of these attributes to work, it is necessary that the "border" attribute (for example, "border=1") also be used so that the border will be displayed.
272:69 | Error | The attribute value "#111111" for the "borderColor" 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. <TABLE id=AutoNumber1 style="BORDER-COLLAPSE: collapse" borderColor=#111111 height=172 cellSpacing=0 cellPadding=0 width="83%" border=0>
272:23 | Message (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.
272:23 | Message (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.
272:57 | Message (Microsoft Internet Explorer) | [1] The "bordercolor", "bordercolordark", and "bordercolorlight" attributes for the "TABLE" element are not HTML or XHTML attributes and are currently only supported by Internet Explorer. For instance, Netscape 4.0 does not support these attributes. You've used at least one of these attributes in this "TABLE" tag.
272:77 | Message (General Compatibility) | [5] The "height" attribute for the "TABLE" element is not an official HTML or XHTML attribute and is currently only supported by some versions of Internet Explorer and Netscape. Note that Netscape 6.0+ does not support this attribute.
276:2 | Error | [47] Nested lists should be contained in an "li" tag. <UL><B>
276:6 | Message (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.
277:6 | Message (Good Style) | [31] The "B" tag was opened in another "B" tag (which was opened in line 276). Normally this does not cause any problems, but some may not consider it to be good style.
278:6 | Message (Good Style) | [31] The "B" tag was opened in another "B" tag (which was opened in line 276). Normally this does not cause any problems, but some may not consider it to be good style.

312:30 | Message (Deprecated) | [9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="right", consider using the CSS "text-align: right" instead.
315:151 | Warning | The "A" tag contains no link text. Though it is not technically required, it is recommended that all "A" elements contain appropriate link text or an appropriate element, like "img".
319:141 | Warning | At least one character (codepoint) between 128 and 159 (inclusive) was found on line 319. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows.

| 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.
| Comment | You 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.
| Comment | You can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.

Line:char | Type | Message 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.
5:2 | Message (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.
5:8 | Message (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.
49:2 | Message (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.
52:35 | Message (General Compatibility) | [5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
121:3 | Message (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.
123:8 | Message (Deprecated) | [9] The "height" and "width" attributes for the "td" and "th" elements are deprecated in HTML 4.01 and XHTML in favor of using style sheets.
133:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
155:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
173:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
204:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
227:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
232:30 | Warning | At least one character (codepoint) between 128 and 159 (inclusive) was found on line 232. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. If you are wanting the euro sign, then it is recommended that the character reference "&#8364;" be used. Another option would be to use the entity reference "&euro;".
244:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
259:5 | Error | The "td" tag must have an end tag (</td>) but the end tag was not found. <td valign="top" class="centrale">
266:14 | Message (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.
270:2 | Message | The "P" element is empty. Consider removing this element if it is not needed. If you are wanting to add additional margin space between elements, consider using the "margin" CSS properties like "margin", "margin-top", and "margin-bottom" instead. Paragraph elements should be used to denote paragraphs and not for presentational formatting.
272:2 | Error | [47] The "UL" element may directly contain only the "li" element. The "P" element is not allowed here. <P><A href="#Mezziditrasporto" name=top></A></P>
272:43 | Warning | The "A" tag contains no link text. Though it is not technically required, it is recommended that all "A" elements contain appropriate link text or an appropriate element, like "img".
273:6 | Message (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.
284:78 | Error | The end tag for "B" (opened in line 284) should appear before the end tag for "P" (nesting error). <P class=fasciamarroncino><B>Mezzi di trasporto<A name=Mezziditrasporto></A></P></B>
285:112 | Warning | At least one character (codepoint) between 128 and 159 (inclusive) was found on line 285. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. If you are wanting the euro sign, then it is recommended that the character reference "&#8364;" be used. Another option would be to use the entity reference "&euro;".
285:4 | Message (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.
285:4 | Message (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.
286:254 | Warning | The "A" tag contains no link text. Though it is not technically required, it is recommended that all "A" elements contain appropriate link text or an appropriate element, like "img".
287:30 | Message (Deprecated) | [9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="right", consider using the CSS "text-align: right" instead.
290:103 | Warning | The "B" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
295:264 | Message (Good Style) | It is usually best not to specify the actual index document name "index.htm". Consider using href="http://www.evaa.org/evaa/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
301:71 | Warning | The "B" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.

| 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.
| Comment | You can ignore the nesting errors by turning off the option to check HTML tag nesting. However, it is recommended that you leave this feature enabled. This option is in CSE HTML Validator's Validator Engine Options.
| Comment | You 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.

| 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.
| Comment | You 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.
| Comment | You can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
| Comment | You 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.

--- | --- | ---
| 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.
5:2 | Message (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.
5:8 | Message (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.
49:2 | Message (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.
52:35 | Message (General Compatibility) | [5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
121:3 | Message (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.

--- | --- | ---
| 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.
5:2 | Message (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.
5:8 | Message (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.
49:2 | Message (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.
52:35 | Message (General Compatibility) | [5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
121:3 | Message (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.
123:8 | Message (Deprecated) | [9] The "height" and "width" attributes for the "td" and "th" elements are deprecated in HTML 4.01 and XHTML in favor of using style sheets.
133:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
155:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.

227:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
232:30 | Warning | At least one character (codepoint) between 128 and 159 (inclusive) was found on line 232. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. If you are wanting the euro sign, then it is recommended that the character reference "&#8364;" be used. Another option would be to use the entity reference "&euro;".
244:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.

273:5 | Message (Deprecated) | [9] The "bgcolor" attribute for the "TD" and "th" elements is 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: #fcf5e2".

278:2 | Message (Good Style) | [7] A heading has been used without previously using the higher heading levels. Some HTML authors consider this bad style. For example, if "h4" is used, then "h1", "h2", and "h3" should have already been used, in that order.

49:2 | Message (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.
52:35 | Message (General Compatibility) | [5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this 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.
| Comment | You 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.
| Comment | You can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
| Comment | You 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.

| 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.
| Comment | You 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.

Line:char | Type | Message 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.
5:2 | Message (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.
5:8 | Message (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.
49:2 | Message (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.
52:35 | Message (General Compatibility) | [5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
121:3 | Message (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.
123:8 | Message (Deprecated) | [9] The "height" and "width" attributes for the "td" and "th" elements are deprecated in HTML 4.01 and XHTML in favor of using style sheets.
133:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
155:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.

227:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.
232:30 | Warning | At least one character (codepoint) between 128 and 159 (inclusive) was found on line 232. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. If you are wanting the euro sign, then it is recommended that the character reference "&#8364;" be used. Another option would be to use the entity reference "&euro;".
244:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.

273:5 | Message (Deprecated) | [9] The "bgcolor" attribute for the "TD" and "th" elements is 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: #fcf5e2".

| 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.
5:2 | Message (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.
5:8 | Message (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.
49:2 | Message (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.
52:35 | Message (General Compatibility) | [5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
121:3 | Message (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.
123:8 | Message (Deprecated) | [9] The "height" and "width" attributes for the "td" and "th" elements are deprecated in HTML 4.01 and XHTML in favor of using style sheets.
133:43 | Warning | An "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.

| 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.
| Comment | You 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.
| Comment | You can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
| Comment | You 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.

| 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.
| Comment | You 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.
| Comment | You can use the Quick Quote Tool in the editor to quickly enclose all attribute values in quotation marks.
| Comment | You 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.
