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.
3:2	Message	The first tag in the document was out of range. The document has been checked with the assumption that a block of HTML that belongs in a <html> ... </html> section is being validated.
4:2	Warning	HTML 4.01 and XHTML require the "type" attribute for the "style" element to specify the style sheet language. For example, use type="text/css". Note that many browsers may work without this attribute but it is highly recommended that it be used.
12:15	Warning (General) [CSS]	It is recommended that a generic font family name be specified as the last font family name. If the preceding font family names are not available then the browser should fall back to the generic font family name. The generic font family names are serif, sans-serif, cursive, fantasy, and monospace. Be sure not to use quotes around generic font family names.
16:3	Warning	[32] This document should be given a title by using the "title" element in the document's "head" section. HTML 4.01 and XHTML require exactly one "title" element for each document.
18:7	Message (Deprecated)	[9] The "background", "bgcolor", "text", "link", "vlink", and "alink" attributes for the "body" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of the "bgcolor" attribute, consider using the CSS property "background-color". Example: style="background-color: #CCCC99".
22:2	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.
22:63	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.
28:20	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.
31:10	Message (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.
31:26	Message (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).
34:4	Warning	[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).
34:4	Message (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.
41:2	Error	There may be only one "body" section in an HTML or XHTML document. The "body" element has been used 2 times. <body bgcolor="#CCCC99">
42:2	Warning	[56] The "p" tag is contained in a "p" tag that was opened in line 40. This is against the HTML specification and may cause problems with some browsers.
44:50	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.
44:50	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.
46:12	Message (Good Style)	It is usually best not to specify the actual index document name "index.asp". Consider using href="./" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
47:70	Error	The end tag for "a" was found, but "a" was never opened, has been ended too many times, or cannot have an end tag. <font color="#800000">Introduzione</font></span></a></font></span></a> </font>
62:11	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".
66:2	Error	The end tag for "body" (opened in line 41) should appear before the end tag for "p" (nesting error). </p>
76:28	Warning (General) [CSS]	It is recommended that a generic font family name be specified as the last font family name. If the preceding font family names are not available then the browser should fall back to the generic font family name. The generic font family names are serif, sans-serif, cursive, fantasy, and monospace. Be sure not to use quotes around generic font family names.
76:61	Warning (General) [CSS]	It is recommended that a generic font family name be specified as the last font family name. If the preceding font family names are not available then the browser should fall back to the generic font family name. The generic font family names are serif, sans-serif, cursive, fantasy, and monospace. Be sure not to use quotes around generic font family names.
76:61	Error (General) [CSS]	The font family name "&quot" must be enclosed in quotation marks (single or double) because the name contains spaces, special characters, or doesn't begin with an alphabetic character. <span style="font-family: Symbol">·<span style="font:7.0pt "Times New Roman"">
76:67	Error (Parsing) [CSS]	Bad style format, cannot find the colon separating the style property from its value. <span style="font-family: Symbol">·<span style="font:7.0pt "Times New Roman"">
76:55	Message (General) [CSS]	The following typeface may not be available on a significant number of browsers: "&quot". Also, check the spelling of the typeface name.

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.

	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 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.

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.
3:2	Message	The first tag in the document was out of range. The document has been checked with the assumption that a block of HTML that belongs in a <html> ... </html> section is being validated.
4:2	Warning	HTML 4.01 and XHTML require the "type" attribute for the "style" element to specify the style sheet language. For example, use type="text/css". Note that many browsers may work without this attribute but it is highly recommended that it be used.
12:15	Warning (General) [CSS]	It is recommended that a generic font family name be specified as the last font family name. If the preceding font family names are not available then the browser should fall back to the generic font family name. The generic font family names are serif, sans-serif, cursive, fantasy, and monospace. Be sure not to use quotes around generic font family names.
16:3	Warning	[32] This document should be given a title by using the "title" element in the document's "head" section. HTML 4.01 and XHTML require exactly one "title" element for each document.
18:7	Message (Deprecated)	[9] The "background", "bgcolor", "text", "link", "vlink", and "alink" attributes for the "body" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of the "bgcolor" attribute, consider using the CSS property "background-color". Example: style="background-color: #CCCC99".
22:2	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.
22:63	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.
28:20	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.
31:10	Message (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.
31:26	Message (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).
34:4	Warning	[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).
34:4	Message (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.
42:2	Error	There may be only one "body" section in an HTML or XHTML document. The "body" element has been used 2 times. <body bgcolor="#CCCC99">
43:2	Warning	[56] The "p" tag is contained in a "p" tag that was opened in line 40. This is against the HTML specification and may cause problems with some browsers.
45:50	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.
45:50	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.
47:12	Message (Good Style)	It is usually best not to specify the actual index document name "index.asp". Consider using href="./" instead. Visit http://webtips.dan.info/subdir.html#LinkHome for more information about why this is recommended.
48:70	Error	The end tag for "a" was found, but "a" was never opened, has been ended too many times, or cannot have an end tag. <font color="#800000">Introduzione</font></span></a></font></span></a> </font>
63:11	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".
67:2	Error	The end tag for "body" (opened in line 42) should appear before the end tag for "p" (nesting error). </p>
80	Error	This 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 style="margin-top:6.0pt;margin-right:72.0pt;margin-bottom:0cm;margin-left:
81:8	Warning (General) [CSS]	The "margin-bottom" property has already been defined in this style rule. A property should only be defined once per rule.
81:78	Warning	At least one character (codepoint) between 128 and 159 (inclusive) was found on line 81. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. Consider using "’" instead of this character.
82:14	Warning	At least one character (codepoint) between 128 and 159 (inclusive) was found on line 82. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. Consider using "“" instead of this character.
82:16	Message (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.
83:79	Warning	At least one character (codepoint) between 128 and 159 (inclusive) was found on line 83. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. Consider using "”" instead of this character.
85:3	Warning	At least one character (codepoint) between 128 and 159 (inclusive) was found on line 85. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. Consider using "’" instead of this character.
92:28	Warning (General) [CSS]	It is recommended that a generic font family name be specified as the last font family name. If the preceding font family names are not available then the browser should fall back to the generic font family name. The generic font family names are serif, sans-serif, cursive, fantasy, and monospace. Be sure not to use quotes around generic font family names.
92:28	Error (General) [CSS]	The font family name "&quot" must be enclosed in quotation marks (single or double) because the name contains spaces, special characters, or doesn't begin with an alphabetic character. -<span style="font:7.0pt "Times New Roman"">         </span>
92:34	Error (Parsing) [CSS]	Bad style format, cannot find the colon separating the style property from its value. -<span style="font:7.0pt "Times New Roman"">         </span>
92:22	Message (General) [CSS]	The following typeface may not be available on a significant number of browsers: "&quot". Also, check the spelling of the typeface name.
94:7	Warning	At least one character (codepoint) between 128 and 159 (inclusive) was found on line 94. These codepoints are commonly found in Windows character sets like Windows-1252 but may not work for everyone, especially those not using Windows. Consider using "’" instead of this character.

137	Error	Terminating validation due to too many warnings. Please correct the previous warnings and recheck the document. HTML Validator is currently set to stop after 20 warnings.
	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.

15:2	Message (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.
17:10	Message (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.

21:2	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.
35:16	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.
74:35	Message (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.
81:61	Error	The "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">
81:4	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.
81:4	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.

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.
15:2	Message (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.
17:10	Message (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.
20:2	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.
24:2	Error	The "div" tag must have an end tag (</div>) but the end tag was not found. <div class="width">
25:4	Error	The "div" tag must have an end tag (</div>) but the end tag was not found. <div class="minwidth">
34:16	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.
73:35	Message (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.
82:61	Error	The "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">
82:4	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.
82:4	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.
94:14	Error	The "dt" tag must have an end tag (</dt>) but the end tag was not found. <dt class="primo"> <a href="index_collezioni.htm">Le collezioni</a> <br>
117:12	Error	The end tag for "dt" (opened in line 94) should appear before the end tag for "dl" (nesting error). </dl></td>
120:36	Message (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.
130:15	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.
130:15	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.
130:15	Message (Deprecated)	[9] The "compact", "start", and "type" attributes for the "ol" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets (use the "list-style-type" CSS property instead).
131:40	Message (General) [CSS]	Found the Microsoft Office property "mso-list". HTML Validator ignores these proprietary properties that begin with "mso-". This message is displayed only once. There may be other proprietary properties.
131:64	Message (General) [CSS]	Found the property "tab-stops". This is likely a Microsoft proprietary CSS property. HTML Validator ignores this property. This message is displayed only once. There may be other "tab-stops" proprietary properties.
132:20	Message (Deprecated)	[9] The "align" attribute is deprecated in HTML 4.01 and XHTML in favor of using style sheets. Instead of align="left", consider using the CSS "text-align: left" instead.
157:4	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.
158:4	Message	The "p" element is empty. Consider removing this element if it is not needed.

Paragraph elements should be used to denote paragraphs and not for presentational formatting.

	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.
15:2	Message (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.
17:11	Message (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.

31:11	Message (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. This is the last time that this message will be generated. There may be more places where a foreground color was defined without a background color.
34:2	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.
48:16	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.
87:35	Message (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.
92:61	Error	The "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">
92:4	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.
92:4	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.
132:36	Message (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.
134:10	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.
138:16	Message (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.
155:12	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.

	Comment (Accessibility Tips) [ACCESSIBILITY]	This program can help you make your web pages more accessible.

123:16	Message (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.
126:29	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.
144:69	Warning	The "strong" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
144:77	Warning	The "em" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
166:28	Message (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).
169:23	Message (Deprecated)	[9] The "compact" and "type" attributes for the "UL" element are deprecated in HTML 4.01 and XHTML in favor of using style sheets (use the "list-style-type" CSS property instead of the "type" attribute).
240:20	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.
240:20	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.

	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.
15:2	Message (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.
19:2	Message (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.
23:2	Message (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.
27:2	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.
41:16	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.
80:35	Message (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.
85:61	Error	The "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">
85:4	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.
85:4	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.
99:14	Error	The "dt" tag must have an end tag (</dt>) but the end tag was not found. <dt class="primo"> <a href="index_collezioni.htm">Le collezioni</a> <br>
119:11	Error	The end tag for "dt" (opened in line 99) should appear before the end tag for "dl" (nesting error). </dl>
124:36	Message (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.
129:14	Message (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.
134:19	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.
179:84	Warning	The "strong" element contains no text and may be useless. Consider removing this element or placing text in it so that it contains text.
189:4	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.
	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.
