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.
5:2Message (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.
5:8Message (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.
49:2Message (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.
52:35Message (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.
115:3Message (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.
117:8Message (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.
127:43WarningAn "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.
149:43WarningAn "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.
167:43WarningAn "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.
198:43WarningAn "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.
221:43WarningAn "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.
226:30WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 226. 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;".
238:43WarningAn "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.
260:3Message (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.
265:7Message (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.
265:56Message (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.

 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 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 (1138, 605 unique): abiotica (1x), Abitante (1x), accezioni (1x), acido (1x), adiacenti (1x), aerea (1x), affermazione (1x), agenti (1x), Agenzia (1x), Agenzie (1x), albero (1x), alimentano (1x), all'interno (1x), allo (1x), alluminio (1x), altezza (1x), aminoacidi (1x), animali (1x), Annali (1x), anni (1x), antropica (1x), antropico (1x), appartenenze (1x), arborea (1x), aree (1x), argille (1x), artificialmente (1x), aspetto (1x), associare (1x), attraversati (1x), avente (1x), azionato (1x), azione (1x), azioni (1x), bacini (1x), basate (1x), basato (1x), Batteri (1x), batterica (1x), bauxiti (1x), bauxitiche (1x), BeginNoIndex (1x), behavior.css (1x), benefìci (1x), beni (1x), Biblioteca (1x), biochimica (1x), biodegradabile (1x), Biodegradazione (1x), Biodisco (1x).

 Comment (Search Engine)[113] Random Search Engine Tip #20 - Don't use keyword stuffing. Keyword stuffing is inserting blocks of keywords to try to increase a page's rankings by increasing its keyword density. This is considered spamming and can easily be detected. Example: keyword1 keyword1 keyword1 keyword2 keyword2 keyword2 keyword3 keyword3 keyword3, etc.
 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.

5:2Message (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.
5:8Message (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.
49:2Message (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.
52:35Message (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.
120:3Message (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.
122:8Message (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.
132:43WarningAn "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.
154:43WarningAn "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.
172:43WarningAn "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.
203:43WarningAn "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.
226:43WarningAn "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.
231:30WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 231. 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;".
243:43WarningAn "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.
265:5Message (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.
268:22WarningThe "h1" header element contains no text. Header elements are important and should contain appropriate header text.
274:2MessageThe "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.
275:25Message (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.
277:2MessageThe "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.
283:180WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 283. 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;".
283:408Message (Tips)[6] Email spam is a huge problem nowadays. Be aware that mailto email addresses are easily harvested for spam lists by automated programs. Consider alternate, but less user-friendly, ways of distributing email addresses if spam is a concern.
312:2MessageThe "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.

 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 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.

265:44Message (General Compatibility)HTML 4.01 and XHTML allow the "name" attribute with the "form" element for backward compatibility. However, the "id" attribute should be used to identify elements. Previously, HTML 4.0 did not allow the "name" attribute with the "form" element. It is recommended that both "name" and "id" attributes be used when using the "form" element. The values for both of these attributes should be identical.

267:63Message (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.

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.

5:2Message (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.
5:8Message (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.
49:2Message (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.
52:35Message (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.
121:3ErrorThis table doesn't appear to have the same number of cells in each of its 2 rows. Number of cells in each row, starting with the first row: 3, 2. Note that for the purposes of this message, a table cell with a "colspan" or "rowspan" value greater than 1 is considered to be multiple cells.

<table border="0" cellspacing="0" cellpadding="0" class="tabellaContenuti">
 

121:3Message (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.
123:8Message (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.
133:43WarningAn "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.
155:43WarningAn "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.
173:43WarningAn "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.
204:43WarningAn "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.
227:43WarningAn "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.
232:30WarningAt 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;".

259:5ErrorThe "td" tag must have an end tag (</td>) but the end tag was not found.

266:14Message (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.
275:32WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 275. 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;".
275:4Message (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.
275:4Message (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.
275:375Message (Good Style)[7] Underlining text may confuse your visitors because most browsers use underlining to emphasize hyperlinks.
275:375Message (Deprecated)[9] The "U" element is deprecated in HTML 4.01 and XHTML in favor of using style sheets ("text-decoration: underline").
276:30Message (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.
279:80WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 279. 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;".
288:2ErrorThe "td" element cannot be used here. It is nested in another "td" tag and cannot be nested. Has the previous "td" element been ended? This element may be contained in "tr". This element may not be contained in "td" and "th".

271:2Warning[28] The "P" tag is contained in a "A" tag (which was opened in line 270). This may be acceptable for some browsers (such as Internet Explorer and Netscape), but HTML 4.01 and XHTML do not allow this. It may also cause problems or unexpected page rendering for more compliant browsers such as Firefox, Mozilla, and Opera. Possible solutions: 1. Close the "A" tag before using the "P" tag. Depending on the correct usage of the closed tag, you may be able to reopen it after using the "P" tag; 2. Eliminate the "P" tag; or 3. Reorder the "P" and "A" tags.
271:2MessageThe "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.

5:2Message (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.
5:8Message (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.
49:2Message (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.
52:35Message (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.
121:3ErrorThis table doesn't appear to have the same number of cells in each of its 2 rows. Number of cells in each row, starting with the first row: 3, 2. Note that for the purposes of this message, a table cell with a "colspan" or "rowspan" value greater than 1 is considered to be multiple cells.

<table border="0" cellspacing="0" cellpadding="0" class="tabellaContenuti">
 

121:3Message (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.
123:8Message (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.
133:43WarningAn "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.

232:30WarningAt 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;".
244:43WarningAn "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.
259:5ErrorThe "td" tag must have an end tag (</td>) but the end tag was not found.

<td valign="top" class="centrale">
 

266:14Message (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.
271:2Warning[28] The "P" tag is contained in a "A" tag (which was opened in line 270). This may be acceptable for some browsers (such as Internet Explorer and Netscape), but HTML 4.01 and XHTML do not allow this. It may also cause problems or unexpected page rendering for more compliant browsers such as Firefox, Mozilla, and Opera. Possible solutions: 1. Close the "A" tag before using the "P" tag. Depending on the correct usage of the closed tag, you may be able to reopen it after using the "P" tag; 2. Eliminate the "P" tag; or 3. Reorder the "P" and "A" tags.
271:2MessageThe "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.
282:28Message (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.
283:4Message (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.
283:4Message (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.
285:30Message (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.
290:70WarningThe "B" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
293:76WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 293. 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;".
294:70WarningThe "B" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.

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;".
297:873Message (Good Style)It is usually best not to specify the actual index document name "index.html". Consider using href="http://www.epa.gov/docs/ozone/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
297:1103Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="http://europa.eu.int/comm/environment/ozone/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.

 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 (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 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.

5:2Message (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.
5:8Message (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.
49:2Message (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.
52:35Message (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.
121:3ErrorThis table doesn't appear to have the same number of cells in each of its 2 rows. Number of cells in each row, starting with the first row: 3, 2. Note that for the purposes of this message, a table cell with a "colspan" or "rowspan" value greater than 1 is considered to be multiple cells.

<table border="0" cellspacing="0" cellpadding="0" class="tabellaContenuti">
 

121:3Message (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.
123:8Message (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.
133:43WarningAn "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.

266:14Message (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.
271:2Warning[28] The "P" tag is contained in a "A" tag (which was opened in line 270). This may be acceptable for some browsers (such as Internet Explorer and Netscape), but HTML 4.01 and XHTML do not allow this. It may also cause problems or unexpected page rendering for more compliant browsers such as Firefox, Mozilla, and Opera. Possible solutions: 1. Close the "A" tag before using the "P" tag. Depending on the correct usage of the closed tag, you may be able to reopen it after using the "P" tag; 2. Eliminate the "P" tag; or 3. Reorder the "P" and "A" tags.
271:2MessageThe "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.
280:68WarningThe "STRONG" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
281:4Message (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.
281:4Message (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.
281:834Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="http://www.oieau.fr/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
282:30Message (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.
287:114WarningAt least one character (codepoint) between 128 and 159 (inclusive) was found on line 287. 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;".

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.
279:4Message (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.
279:2116Message (Good Style)It is usually best not to specify the actual index document name "index.html". Consider using href="http://www.library.adelaide.edu.au/guide/sci/Geology/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
279:2363Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="http://www.geosociety.org/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
279:2984Message (Good Style)It is usually best not to specify the actual index document name "index.html". Consider using href="http://atm.geo.nsf.gov/" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended. This is the last time that this message will be generated. There may be other links specifying the actual index document name.
280:30Message (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.
298:2ErrorThe "td" element cannot be used here. It is nested in another "td" tag and cannot be nested. Has the previous "td" element been ended? This element may be contained in "tr". This element may not be contained in "td" and "th".

<td valign="top" width="163" class="colonnaDx">
 

344:4ErrorThe end tag for "td" (opened in line 259) should appear before the end tag for "tr" (nesting error).

</tr>
 

350:3ErrorSomewhere in this document there is a nonexistent internal link to "menu" created by using <a href="#menu"> ... </a>. This link should be removed or it should link to a location in the document that is specified by <a name="menu"> ... </a> or <element id="menu"...>.

 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 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.
