4:2 | 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. |

634:48 | Error (HTML 4.0 Compatibility) | [81] The "align" attribute may not be used with the "div" element in a strict HTML 4.0/4.01 document. Instead of align="left", consider using the CSS "text-align: left" instead. <td id="Contenuti"> <div id="path" align="left"> <a href="default_en.htm">Home</a> |
634:48 | 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. |
639:18 | 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). |
639:18 | Message (Good Style) | [7] The "height" and "width" attributes should be used with the "img" element. Using these attributes generally result in faster and smoother (less jumpy) rendering. Using them is also considered to be good style. |
639:18 | 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. |
639:73 | 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. |
639:73 | 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. |
639:101 | Message (General) [CSS] | The <border-style> value for the "border" property was omitted. This will result in no border being applied because the default of <border-style> is "none". |

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 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="MenuSinistro"> ... </a> or <a name="MenuSinistro" id="MenuSinistro"> ... </a> instead. | |
Comment | You may want to turn off 128-159 character checking if you're sure that these characters will be interpreted and displayed properly by the visiting user agents. This option is in CSE HTML Validator's Validator Engine Options. | |

637:18 | Error (HTML 4.0 Compatibility) | [76] The "center" element should not be used in a strict HTML 4.0/4.01 document. Style sheets should be used instead of this element. Note that you may want to consider using a different DOCTYPE declaration that is more lenient and allows more element, such as an HTML 4.01 transitional DOCTYPE. For example, you may want to use the HTML 4.01 transitional DOCTYPE: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. <center> |
637:18 | Message (Deprecated) | [9] Even though the "center" element is deprecated in HTML 4.01 and XHTML, real-world circumstances may make using this element better than using CSS in some situations. Using CSS may be more complex and may not easily (or at all) give the desired effect of centering blocks like forms and tables. However, AI Internet Solutions still recommends using CSS whenever reasonably possible. |
637:18 | Message (Deprecated) | [9] The "center" element is deprecated in HTML 4.01 and XHTML in favor of using style sheets (to center text use the CSS "text-align: center" instead or align="center" where "align" is not deprecated). Another option is to use <div style="text-align: center">...</div> instead of <center>...</center>, but this may not center tables. The "center" element may become obsolete and unsupported in the future. |
638:20 | 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. |

642:38 | 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). |
642:38 | Message (Good Style) | [7] The "height" and "width" attributes should be used with the "img" element. Using these attributes generally result in faster and smoother (less jumpy) rendering. Using them is also considered to be good style. |
642:38 | 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. |
642:72 | Message (General Compatibility) | [5] Using a percent value for the "height" or "width" attribute with the "img" element may result in inconsistent rendering, especially when the images are in table cells. Note, however, that a percent value for these attributes is valid in HTML 4/XHTML. |

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. | |

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.

639:18 | Error (HTML 4.0 Compatibility) | [76] The "center" element should not be used in a strict HTML 4.0/4.01 document. Style sheets should be used instead of this element. Note that you may want to consider using a different DOCTYPE declaration that is more lenient and allows more element, such as an HTML 4.01 transitional DOCTYPE. For example, you may want to use the HTML 4.01 transitional DOCTYPE: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. <center> |
639:18 | Message (Deprecated) | [9] Even though the "center" element is deprecated in HTML 4.01 and XHTML, real-world circumstances may make using this element better than using CSS in some situations. Using CSS may be more complex and may not easily (or at all) give the desired effect of centering blocks like forms and tables. However, AI Internet Solutions still recommends using CSS whenever reasonably possible. |
639:18 | Message (Deprecated) | [9] The "center" element is deprecated in HTML 4.01 and XHTML in favor of using style sheets (to center text use the CSS "text-align: center" instead or align="center" where "align" is not deprecated). Another option is to use <div style="text-align: center">...</div> instead of <center>...</center>, but this may not center tables. The "center" element may become obsolete and unsupported in the future. |
642:20 | Message (General Compatibility) | The "table" tag is contained in a "center" tag. Different browsers may render this very differently. For example, Internet Explorer 6.0 may center the table cell content (depending on the DOCTYPE) while Internet Explorer 5.5 does not. However, both will center the table itself. If you want to center the table, then align="center" may be used in the "table" tag. |

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. | |

4:2 | 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. |
14:2 | 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. |

89:40 | 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. |

112:10 | 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. |
112:10 | 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. |

709:26 | 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. |

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 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. | |
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 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="MenuSinistro"> ... </a> or <a name="MenuSinistro" id="MenuSinistro"> ... </a> instead. | |

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. |
14:2 | 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. |
23:40 | 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. |
46:67 | 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"> |
46:10 | 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. |
46:10 | 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. |
48:22 | Error (HTML 4.0 Compatibility) | [81] The "align" attribute may not be used with the "div" element in a strict HTML 4.0/4.01 document. Instead of align="center", consider using the CSS "text-align: center" instead. <td><div align="center"><b>SEARCH RESULTS</b></div></td> |
48:22 | 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. |
48:38 | 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. |
51:14 | Error | The "td" tag must have an end tag (</td>) but the end tag was not found. <td id="Contenuti"> <div id="path"> </div> |
58:22 | Error | The end tag for "td" (opened in line 51) should appear before the end tag for "tr" (nesting error). </div></tr> |
70:10 | 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. | |
