Line:charTypeMessage Description
 Message (Web Content Accessibility Guidelines 1.0) [ACCESSIBILITY][73] WCAG 1.0 accessibility checking is disabled.
 Message (Section 508 Accessibility Standards) [ACCESSIBILITY][73] Section 508 accessibility checking is disabled.
5:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
5:8Message (Search Engine)[8] This document's title contains only 2 words. It may be inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
8:2WarningIn XHTML documents, style and script content must not be in a comment because it technically means that the browser will see it as a comment and not as actual style or script content (though browsers are currently forgiving about this). However, not using comments makes your document less compatible with pre HTML 3.2 browsers (but most browsers now in use are HTML 3.2+ compatible). For maximum compatibility, consider putting the style information in an external style sheet. The next best option for XHTML documents is to not put the style information in a comment because this is technically not what you want even though it may work with today's browsers.
11:3Message (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.
22:4Message (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.
23:2Message[41] The "div" tag has no attributes. Attributes are normally used with the "div" element to provide functionality.
24:2Message[41] The "div" tag has no attributes. Attributes are normally used with the "div" element to provide functionality.
25:2Message[41] The "div" tag has no attributes. Attributes are normally used with the "div" element to provide functionality.
26:2Message[41] The "div" tag has no attributes. Attributes are normally used with the "div" element to provide functionality.
30:2Message[41] The "div" tag has no attributes. Attributes are normally used with the "div" element to provide functionality.
30:113Message (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.
31:22Warning[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).
31:22Message (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.
31:22Message (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.
33:2ErrorThis table doesn't appear to have the same number of cells in each of its 2 rows. Number of cells in each row, starting with the first row: 1, 2. Note that for the purposes of this message, a table cell with a "colspan" or "rowspan" value greater than 1 is considered to be multiple cells.

<table border="0">
 

33:2Message (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.
33:2Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.
35:6ErrorThe "th" tag must have an end tag (</th>) but the end tag was not found. In XHTML, all elements not declared as empty (like "b", "p", "span", etc.) must have an end tag. Elements declared as empty (like "br", "img", "input", etc.) can have an end tag or can use the empty element shorthand.

<th rowspan="2" scope="col"><table border="2" align="center" bordercolor="#FFCC66">
 

35:35Message (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.
35:52Message (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.
35:67Message (Microsoft Internet Explorer)[1] The "bordercolor", "bordercolordark", and "bordercolorlight" attributes for the "table" element are not HTML or XHTML attributes and are currently only supported by Internet Explorer. For instance, Netscape 4.0 does not support these attributes. You've used at least one of these attributes in this "table" tag.
38:13ErrorThe attribute "w" does not have a value. All attributes must have a value. This is required for XHTML/XML documents or if the option to require attribute values is enabled.

<th w scope="col"><div align="center"> Number of earthquakes </div></th>
 

38:13ErrorThe "w" attribute is not valid for the "th" element. Some valid attributes for this element are: "abbr", "align", "axes", "axis", "background", "bgcolor", "bordercolor", "bordercolordark", "bordercolorlight", "char", "charoff", "class", "colspan", "contenteditable", "dir", "gradangle", "gradcolor", "headers", "height", "hidefocus", "id", "lang", "language", "nowrap", "onactivate", "onbeforecopy", "onbeforecut", "onbeforepaste", "onclick", "oncontextmenu", "oncopy", "oncut", "ondblclick", "ondeactivate", "ondrag", "ondragend", "ondragenter", "ondragleave", "ondragover", "ondragstart", "ondrop", "onfilterchange", "onfocusin", "onfocusout", "onhelp", "onkeydown", "onkeypress", "onkeyup", "onmousedown", "onmouseenter", "onmouseleave", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onmousewheel", "onmove", "onmoveend", "onmovestart", "onpaste", "onpropertychange", "onselectstart", "rowspan", "scope", "style", "title", "transparency", "unselectable", "valign", "width", "xml:lang", and "xml:space".

<th w scope="col"><div align="center"> Number of earthquakes </div></th>
 

101:6ErrorThe "th" element cannot be used here. It is nested in another "th" tag and cannot be nested. Has the previous "th" element been ended? This element may be contained in "tr". This element may not be contained in "td" and "th".

<th scope="col"><div align="left"><img src="GIS/last_world.jpg" border="0" usemap="#Map" />
 

101:41Warning[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).
101:41Message (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.
103:12Warning[13] HTML 4.01 and XHTML require that the "alt" attribute be used with the "area" element. This attribute lets authors specify alternate text to serve as content when the element cannot be rendered or accessed normally. For example, this attribute is critical for visually impaired users and user agents that cannot display images and image maps.

 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 (8, 8 unique): Chiara (1x), coseismic (1x), EEE (1x), EEEs (1x), GIS (1x), Giulianelli (1x), INQUA (1x), Spernanzoni (1x). Complete list.
 CommentXHTML 1.0 Transitional document detected.
 Comment[24] The XHTML recommendation strongly encourages that an XML declaration be used as the first line (line 1) of every XHTML document. For example, for XHTML and WML documents, something similar to <?xml version="1.0" encoding="UTF-8"?> or simply <?xml version="1.0"?> should be the first line. If you are using HTML Validator's integrated editor, then you can add this from the Tags menu or from the Tag Inserter. However, in practice, correctly using an XML declaration may cause problems, such as triggering Internet Explorer 6's "quirks" mode (which causes non-standards compliant rendering). Because of this, consider not using an XML declaration.
 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/.
 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. For more information about disabling messages, please look at the Configuration section in the documentation.

52:35Message (General Compatibility)[5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well.

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.

5:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
5:8Message (Search Engine)[8] This document's title contains only 4 words. It may be inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
49:2Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.
52:35Message (General Compatibility)[5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.

5:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
49:2Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers.

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.

 Comment (Accessibility Tips) [ACCESSIBILITY]This program can help you make your web pages more accessible. An accessible page is one that more individuals can use, such as individuals who are blind or deaf. It can also increase the usefulness of your web page for individuals who browse the web using slower devices like older computers or wireless devices like cell phones and PDAs. An accessible web site makes good business sense (and possibly good legal sense as well). You can enable or disable accessibility checking in the Validator Engine Options.
 CommentYou can 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 (Search Engine)[113] Random Search Engine Tip #2 - It's a good idea to repeat this document's title, keywords, and search terms in header tags (like "h1", "h2", etc.) and throughout the page. Use CSS to make the headers look good. However, be sure not to change the meaning of the header tags, like making a header look like regular text because that can be considered cheating and may result in your site being penalized.

5:2Message (Search Engine)Tip - A good title is very important for search engine listings. Use many keywords and search terms in the title but make it readable. Don't just stuff keywords in the title. The title should also be something that a user will want to click on when it's listed on a search engine. A good title is also important when a visitor bookmarks a page. Example: <title>Download CSE HTML Validator - Powerful HTML and Link Checking Software for Windows</title>. AI Internet Solutions also recommends that the "title" tag be the first tag inside the "head" section.
5:8Message (Search Engine)[8] This document's title contains only 1 word. It may be inadequate for search engine purposes. A good title is important to your search engine rankings and listings. AI Internet Solutions recommends a title that is 5-15 words in length and that contains a relevant and descriptive phrase. The title should also contain keywords and search terms while remaining readable.
49:2Message (General Compatibility)[5] The "table" element is an official HTML 4.01 and XHTML element but may not be supported by older or nongraphical browsers. Furthermore, nongraphical browsers that do support tables may not support them the way that you expect. However, most browsers used today should support this element.
52:35Message (General Compatibility)[5] PNG images are generally well supported in today's browsers EXCEPT for Microsoft Internet Explorer 6.0 and below. IE 6.0 will not render PNG images correctly in certain cases. Because of the popularity of Internet Explorer, you may want to consider using GIF or JPG images instead, especially when using the transparency features of PNG which IE 6.0 does not support well. Fortunately PNG support has been improved in IE 7.0. This message is displayed only once. There may be other PNG images specified in this document.
117:3Message (Good Style)Consider using the "width" attribute with the "table" element. This is considered to be good style and can cause the table and page to render faster. Note that this is not a deprecated attribute in HTML 4.01 nor XHTML 1.0. It's also a valid XHTML 1.1 attribute.
119:8Message (Deprecated)[9] The "height" and "width" attributes for the "td" and "th" elements are deprecated in HTML 4.01 and XHTML in favor of using style sheets.
129:43WarningAn "href", "id", or "name" attribute should normally be used with the "a" element. If one of these attributes are being set with a script, then consider the accessibility issues of requiring scripting. Disable this message if you do not want to check for this.

264:2MessageThe "P" element is empty. Consider removing this element if it is not needed.
