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.
15:2Message (Microsoft Internet Explorer) [CSS][600] The "behavior" CSS property is not an official CSS property and is only supported by Internet Explorer 5.0+. Firefox, Netscape, Opera, and most other browsers do not support this property.
19:2Message (Good Style) [CSS]When a foreground color is defined, it is recommended that a background color also be defined (by using the "background" or "background-color" property). This helps to avoid conflict with user-defined style sheets and to improve accessibility.
25:2Message (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.
39:16Message (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.
78:35Message (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.
83:61ErrorThe "summary" attribute has an invalid attribute value "". Try using one of the following values: an alphanumeric string or a string.

<table border="0" cellspacing="0" cellpadding="0" summary="" class="TabellaCentrale">
 

83:4Message (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.
83:4Message (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.
127:36Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="./" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
132:16Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="justify", consider using the CSS "text-align: justify" instead.
137:14ErrorThis table doesn't appear to have the same number of cells in each of its 12 rows. Number of cells in each row, starting with the first row: 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 1, 1. 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 align="center" cellpadding=0 cellspacing=0 >
 

137:14Message (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.
137:29Message (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.
152:21Message (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.
240:4MessageThe "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.
 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 have one or more internal links linking to an ID link destination. Browser support for this is currently very poor. Consider using something like <a name="Contenuti"> ... </a> or <a name="Contenuti" id="Contenuti"> ... </a> instead.
 CommentPossibly misspelled words (425, 270 unique): accordo (1x), adeguare (1x), all'interno (1x), all'unit (1x), alle (1x), allo (1x), ambizioso (1x), Attualmente (1x), Bartolomeo (1x), Benvenuto (1x), c'è (1x), Calendario (1x), Camillo (1x), canale (1x), Canavari (1x), Capellini (1x), cariche (1x), caso (1x), che (1x), Checchia (1x), chiamati (1x), chiusura (1x), cioè (1x), classi (1x), Clerici (1x), Cocchi (1x), commento (1x), completa (1x), connesse (1x), consentono (1x), Contatti (1x), contenente (1x), contengono (1x), contenuti (1x), contesto (1x), contestuali (1x), contribuito (1x), corpo (1x), costruire (1x), costruita (1x), costruito (1x), costruzione (1x), creazione (1x), Crema (1x), cultura (1x), culturale (1x), culturali (1x), custodite (1x), dal (1x), dall'Italia (1x).

 Comment (Search Engine)[113] Random Search Engine Tip #16 - Don't use "&id=" as a parameter in URLs as some search engines like Google won't include these URLs in their listings.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)"> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 Comment (Search Engine)[8] <meta name="keywords" content="(actual keyword list)"> should be used in the "head" section to provide a list of keywords that are relevent to this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 CommentAn ICRA RDF label was not found in the "head" section of this document. Browsers that are enabled with this rating system may not display documents that have not been labelled. It is recommended that every page include an ICRA label. For more information, please visit http://www.icra.org/.
 Comment[10] CSE HTML Validator Std/Pro allows you to disable certain messages (like this example message) and groups of related messages by disabling flags. For instance, the [10] at the beginning of this message indicates that you can disable this message by disabling validator flag 10. If you are using HTML Validator's integrated editor, then you can simply use your mouse on this message to open the context menu (usually done by right-clicking the mouse on this message) and select 'Disable Flag 10' to disable this message. For more information about disabling messages, please look at the Configuration section in the documentation.
 CommentCSE HTML Validator Std/Pro allows you to disable many messages on an individual basis without using flags. For instance, you can disable this message by using HTML Validator's integrated editor to open the context menu for this message (usually done by right-clicking the mouse on this message) and selecting 'Options for this Message->Disable Message' to disable this message.

126ErrorThis line contains part of a quoted string that spans more than one line (not recommended) or a quoted string (like an attribute value) that is missing the start or end quotation mark. Check this line for improperly quoted attribute values that may be missing a start or end quotation mark. As currently configured, HTML Validator requires that all quoted strings be contained on one line and have start and end quotation marks. Note that because of inconsistent handling by user agents, it is not recommended that attribute values contain line breaks.

<p align="right" class=MsoNormal Stile2><b><span style='font-size:11.0pt;mso-bidi-font-size:
 

126:48Message (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.
126:56Message (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.

126:56Message (CSS Tips) [CSS]Use the inline "style" attribute sparingly.

127:19Warning (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.

 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.
 CommentYou can allow a quoted string to exist on more than one line by turning on the option to allow multi-line quotes. However, allowing multi-line quotes may make it more difficult to find problems caused by incorrect quoting. This option is in CSE HTML Validator's Validator Engine Options.
 CommentYou have one or more internal links linking to an ID link destination. Browser support for this is currently very poor. Consider using something like <a name="Contenuti"> ... </a> or <a name="Contenuti" id="Contenuti"> ... </a> instead.

15:2Message (Microsoft Internet Explorer) [CSS][600] The "behavior" CSS property is not an official CSS property and is only supported by Internet Explorer 5.0+. Firefox, Netscape, Opera, and most other browsers do not support this property.
19:2Message (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.

33:16Message (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.
72:35Message (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.

76:4Message (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.
76:4Message (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.

132:23Message (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.

133:24Warning[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).
133:24Message (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.

 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.
15:2Message (Microsoft Internet Explorer) [CSS][600] The "behavior" CSS property is not an official CSS property and is only supported by Internet Explorer 5.0+. Firefox, Netscape, Opera, and most other browsers do not support this property.
20:2Message (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.
34:16Message (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.
73:35Message (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.
78:61ErrorThe "summary" attribute has an invalid attribute value "". Try using one of the following values: an alphanumeric string or a string.

<table border="0" cellspacing="0" cellpadding="0" summary="" class="TabellaCentrale">
 

78:4Message (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.
78:4Message (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.
79:6ErrorThe "tr" tag must have an end tag (</tr>) but the end tag was not found.

<tr>
 

90:14ErrorThe "dt" tag must have an end tag (</dt>) but the end tag was not found.

117:2ErrorThe end tag for "dt" (opened in line 90) should appear before the end tag for "dl" (nesting error).

120:8ErrorThe "td" tag must have an end tag (</td>) but the end tag was not found.

<td id="Contenuti"><!-- Blocco centrale della pagina -->
 

122:36Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="./" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
129:14Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="justify", consider using the CSS "text-align: justify" instead.
136:46Message (General) [CSS]The "style" attribute has been used but a default style sheet language has not been defined (note that HTML Validator would not see this declaration if it is sent as an HTTP header by a web server). HTML 4.01 and XHTML require this for correct documents. However, for all practical purposes, leaving it out is very unlikely to cause problems. If you still want to define a default style sheet language, then include this in the "head" section of your document to specify "text/css" as the default style sheet language: <meta http-equiv="Content-Style-Type" content="text/css">. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. Because this issue is very unlikely to cause problems, consider ignoring or disabling this message. See http://www.w3.org/TR/html4/present/styles.html#default-style for more information.
136:46Message (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.
137:56Message (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.
140:111Message (General) [CSS]Found the Microsoft Office property "mso-spacerun". HTML Validator ignores these proprietary properties that begin with "mso-". This message is displayed only once. There may be other proprietary properties.

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.

378:4MessageThe "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.
 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.
 CommentThe ampersand '&' is an escape character in HTML. If you want to actually use the ampersand in your HTML document, then the character entity reference '&amp;' should be used instead of the actual ampersand character.
 CommentYou have one or more internal links linking to an ID link destination. Browser support for this is currently very poor. Consider using something like <a name="Contenuti"> ... </a> or <a name="Contenuti" id="Contenuti"> ... </a> 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 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.
 CommentYou can allow a quoted string to exist on more than one line by turning on the option to allow multi-line quotes. However, allowing multi-line quotes may make it more difficult to find problems caused by incorrect quoting. This option is in CSE HTML Validator's Validator Engine Options.

20:2Message (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.
35:16Message (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.
74:35Message (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.

79:4Message (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.
79:4Message (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.
127:36Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="./" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
132:7Message (Deprecated)[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="justify", consider using the CSS "text-align: justify" instead.
145:41Message (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.
147:19Message (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.
176:4MessageThe "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.

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.

 Message (Section 508 Accessibility Standards) [ACCESSIBILITY][73] Section 508 accessibility checking is disabled.
15:2Message (Microsoft Internet Explorer) [CSS][600] The "behavior" CSS property is not an official CSS property and is only supported by Internet Explorer 5.0+. Firefox, Netscape, Opera, and most other browsers do not support this property.
25:2Message (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.
39:16Message (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.
78:35Message (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.
83:61ErrorThe "summary" attribute has an invalid attribute value "". Try using one of the following values: an alphanumeric string or a string.

<table border="0" cellspacing="0" cellpadding="0" summary="" class="TabellaCentrale">
 

83:4Message (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.
83:4Message (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.
85:8ErrorThe "td" tag must have an end tag (</td>) but the end tag was not found.

<td id="MenuSinistro"><!-- menu' di Navigazione principale -->
 

95:14ErrorThe "dt" tag must have an end tag (</dt>) but the end tag was not found.

121:11ErrorThe end tag for "dt" (opened in line 95) should appear before the end tag for "dl" (nesting error).

</dl>
 

124:8ErrorThe "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 id="Contenuti"><!-- Blocco centrale della pagina -->
 

126:36Message (Good Style)It is usually best not to specify the actual index document name "index.htm". Consider using href="./" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
141:242Message (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.
161:31Message (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.
164:9Message (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.
165:26Message (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.
182:52WarningThe "font" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
182:52Message (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).
187:25WarningThe "font" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
191:27WarningThe "font" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
209:27WarningThe "font" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
213:101ErrorA quoted string (like an attribute value) cannot be immediately followed by text. It must be followed by a space or by the end of the tag. Is there a missing space character?

<p><a href="felcedidasc.html" target="_blank"><img src="felce_pic.jpg" alt=""width="90" height="121" border="2"></a>
 

223:5ErrorThe "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 id="MenuDestro">
 

225:9MessageThe "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.
258:4MessageThe "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 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.
 CommentPossibly misspelled words (35, 25 unique): Agenzia (1x), alla (1x), behavior.css (1x), BodyTotale (1x), dell'Ambiente (1x), di (1x), endif (1x), italian (1x), Italiano (1x), lte (1x), MenuLeft (1x), menuSx (1x), Miscellanea (1x), navigazione (1x), Protezione (1x), Sei (1x), Servizi (1x), SiteMap (1x), stylesheet (1x), Tecnici (1x), utilit (1x), Vai (1x), BeginNoIndex (3x), EndNoIndex (3x), APAT (7x).

 Comment (Search Engine)[113] Random Search Engine Tip #12 - Many elements support the "title" attribute that is used for annotation (do not confuse the "title" element with the "title" attribute). Consider annotating tags like "a" with something like title="Read about <keywords>". Annotate with keywords and search terms. Some browsers, like Firefox, will also display the value of the "title" attribute when the user hovers the mouse over content with a "title" attribute.
 Comment (Search Engine)[8] <meta name="description" content="(actual description)"> should be used in the "head" section to provide a brief description of what is contained on this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 Comment (Search Engine)[8] <meta name="keywords" content="(actual keyword list)"> should be used in the "head" section to provide a list of keywords that are relevent to this page. This information is used by many search engines when indexing a site. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter.
 CommentAn ICRA RDF label was not found in the "head" section of this document. Browsers that are enabled with this rating system may not display documents that have not been labelled. It is recommended that every page include an ICRA label. For more information, please visit http://www.icra.org/.
