Notes and Potential Issues

The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.

  1. Warning DOCTYPE Override in effect!

    The detected DOCTYPE Declaration "<!DOCTYPE html>" has been suppressed and the DOCTYPE for "HTML 4.01 Transitional" inserted instead, but even if no errors are shown below the document will not be Valid until you update it to reflect this new DOCTYPE.

Validation Output: 50 Errors

  1. Error Line 12, Column 16: there is no attribute "CHARSET"
    	<meta charset="UTF-8">

    You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

    This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.

    How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the <embed> element to incorporate flash media in a Web page, see the FAQ item on valid flash.

  2. Error Line 12, Column 23: required attribute "CONTENT" not specified
    	<meta charset="UTF-8">

    The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

    Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.

  3. Warning Line 20, Column 135: NET-enabling start-tag requires SHORTTAG YES
    …Andalucia 24 Horas &raquo; Feed" href="http://www.andalucia24horas.com/feed" />

    For the current document, the validator interprets strings like <FOO /> according to legacy rules that break the expectations of most authors and thus cause confusing warnings and error messages from the validator. This interpretation is triggered by HTML 4 documents or other SGML-based HTML documents. To avoid the messages, simply remove the "/" character in such contexts. NB: If you expect <FOO /> to be interpreted as an XML-compatible "self-closing" tag, then you need to use XHTML or HTML5.

    This warning and related errors may also be caused by an unquoted attribute value containing one or more "/". Example: <a href=http://w3c.org>W3C</a>. In such cases, the solution is to put quotation marks around the value.

  5. Error Line 21, Column 152: document type does not allow element "LINK" here
    … &raquo; Comments Feed" href="http://www.andalucia24horas.com/comments/feed" />

    The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).

    One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).

    The Validator found an end tag for the above element, but that element is not currently open. This is often caused by a leftover end tag from an element that was removed during editing, or by an implicitly closed element (if you have an error related to an element being used where it is not allowed, this is almost certainly the case). In the latter case this error will disappear as soon as you fix the original problem.

    You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

    This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.

    You have used the element named above in your document, but the document type you are using does not define an element of that name. This error is often caused by:

    • incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Frameset" document type to get the "<frameset>" element),
    • by using vendor proprietary extensions such as "<spacer>" or "<marquee>" (this is usually fixed by using CSS to achieve the desired effect instead).
    • by using upper-case tags in XHTML (in XHTML attributes and elements must be all lower-case).
