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 Character Encoding mismatch!

    The character encoding specified in the HTTP header (utf-8) is different from the value in the <meta> element (iso-8859-1). I will use the value from the HTTP header (utf-8) for this validation.

  2. Warning Mismatch between Public and System identifiers in the DOCTYPE declaration

    This document uses an inconsistent DOCTYPE declaration. The Public Identifier -//W3C//DTD HTML 4.01 Transitional//EN declares the HTML 4.01 Transitional document type, but the associated System Identifier http://www.w3.org/TR/html40/loose.dtd does not match this document type.

    The recommended System Identifier for HTML 4.01 Transitional is http://www.w3.org/TR/html4/loose.dtd.

    The safest way to use a correct DOCTYPE declaration is to copy and paste one from the recommended list and avoid editing that part of your markup by hand.

  1. Warning Line 59, Column 52: NET-enabling start-tag requires SHORTTAG YES
            <meta name="author" content="Susan McLean" />

    The sequence <FOO /> can be interpreted in at least two different ways, depending on the DOCTYPE of the document. For HTML 4.01 Strict, the '/' terminates the tag <FOO (with an implied '>'). However, since many browsers don't interpret it this way, even in the presence of an HTML 4.01 Strict DOCTYPE, it is best to avoid it completely in pure HTML documents and reserve its use solely for those written in XHTML.

  2. Warning Line 60, Column 54: NET-enabling start-tag requires SHORTTAG YES
            <meta name="operator" content="manoj.c.nair" />

    The sequence <FOO /> can be interpreted in at least two different ways, depending on the DOCTYPE of the document. For HTML 4.01 Strict, the '/' terminates the tag <FOO (with an implied '>'). However, since many browsers don't interpret it this way, even in the presence of an HTML 4.01 Strict DOCTYPE, it is best to avoid it completely in pure HTML documents and reserve its use solely for those written in XHTML.

  3. Error Line 60, Column 54: document type does not allow element "META" here
            <meta name="operator" content="manoj.c.nair" />

    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).

  4. Warning Line 61, Column 55: NET-enabling start-tag requires SHORTTAG YES

    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).

  12. Error Line 68, Column 11: end tag for element "HEAD" which is not open
        </head>

    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.

    If this error occurred in a script section of your document, you should probably read this FAQ entry.

    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.

    The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.

    One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").

    You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include:

    • putting text directly in the body of the document without wrapping it in a container element (such as a <p>aragraph</p>), or

    You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include:

    • putting text directly in the body of the document without wrapping it in a container element (such as a <p>aragraph</p>), or
    • forgetting to quote an attribute value (where characters such as "%" and "/" are common, but cannot appear without surrounding quotes), or
    • using XHTML-style self-closing tags (such as <meta ... />) in HTML 4.01 or earlier. To fix, remove the extra slash ('/') character. For more information about the reasons for this, see Empty elements in SGML, HTML, XML, and XHTML.

    You have used a character that is not considered a "name character" in an attribute value.
