Below are all the validator's error messages for which we have an "explanation".
This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.
Check that you are using a proper syntax for your comments, e.g: <!-- comment here -->. This error may appear if you forget the last "--" to close one comment, therefore including the rest of the content in your comment.
Did you forget to close a (double) quote mark?
This error may appear if you are using a bad syntax for your comments, such as "<!invalid comment>" The proper syntax for comments is <!-- your comment here -->.
This error may appear when the validator receives an empty document. Please make sure that the document you are uploading is not empty, and report any discrepancy.
You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include:
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 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>").
The next message, "start tag was here"
points to the particular instance of the tag in question); the
positional indicator points to where the validator expected you to close the
tag.
This is not an error, but rather a pointer to the start tag of the element the previous error referred to.
You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".
This is not an error, but rather a pointer to the start tag of the element the previous error referred to.
Most likely, you nested tags and closed them in the wrong order. For example <p><em>...</p> is not acceptable, as <em> must be closed before <p>. Acceptable nesting is: <p><em>...</em></p>
Another possibility is that you used an element which requires a child element that you did not include. Hence the parent element is "not finished", not complete. For instance, in HTML the <head> element must contain a <title> child element, lists require appropriate list items (<ul> and <ol> require <li>; <dl> requires <dt> and <dd>), and so on.
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:
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.
You have used a character that is not considered a "name character" in an attribute value. Which characters are considered "name characters" varies between the different document types, but a good rule of thumb is that unless the value contains only lower or upper case letters in the range a-z you must put quotation marks around the value. In fact, unless you have extreme file size requirements it is a very very good idea to always put quote marks around your attribute values. It is never wrong to do so, and very often it is absolutely necessary.
An attribute name (and some attribute values) must start with one of a restricted set of characters. This error usually indicates that you have failed to add a closing quotation mark on a previous attribute value (so the attribute value looks like the start of a new attribute) or have used an attribute that is not defined (usually a typo in a common attribute name).
"VI delimiter" is a technical term for the equal sign. This error message means that the name of an attribute and the equal sign cannot be omitted when specifying an attribute. A common cause for this error message is the use of "Attribute Minimization" in document types where it is not allowed, in XHTML for instance.
How to fix: For attributes such as compact, checked or selected, do not write e.g <option selected ... but rather <option selected="selected" ...
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.
Have you forgotten the "equal" sign marking the separation
between the attribute and its declared value?
Typical syntax is attribute="value".
You have specified an attribute more than once. Example: Using
the "height" attribute twice on the same
"img" tag.
This error almost always means that you've forgotten a closing quote on an attribute value. For instance, in:
<img src="fred.gif>
<!-- 50 lines of stuff -->
<img src="joe.gif">
The "src" value for the first
<img> is the entire
fifty lines of stuff up to the next double quote, which probably
exceeds the SGML-defined
length limit for HTML
string literals. Note that the position indicator in the error
message points to where the attribute value ended — in
this case, the "joe.gif" line.
The value of an attribute contained something that is not allowed by
the specified syntax for that type of attribute. For instance, the
“selected” attribute must be
either minimized as “selected”
or spelled out in full as “selected="selected"”; the variant
“selected=""” is not allowed.
It is possible that you violated the naming convention for this attribute.
For example, id and name attributes must begin with
a letter, not a digit.
This attribute can not take a space-separated list of words as a value, but only one word ("token"). This may also be caused by the use of a space for the value of an attribute which does not permit it.
The value of this attribute should be a number, and you probably used a wrong syntax.
It is possible that you violated the naming convention for this attribute.
For example, id and name attributes must begin with
a letter, not a digit.
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>.
The value of the attribute is defined to be one of a list of possible
values but in the document it contained something that is not allowed
for that type of attribute. For instance, the “selected” attribute must be either
minimized as “selected”
or spelled out in full as “selected="selected"”; a value like
“selected="true"” is not
allowed.
Check that you are using a proper syntax for your comments, e.g: <!-- comment here -->. This error may appear if you forget the last "--" to close one comment, and later open another.
You have used an illegal character in your text. HTML uses the standard UNICODE Consortium character repertoire, and it leaves undefined (among others) 65 character codes (0 to 31 inclusive and 127 to 159 inclusive) that are sometimes used for typographical quote marks and similar in proprietary character sets. The validator has found one of these undefined characters in your document. The character may appear on your browser as a curly quote, or a trademark symbol, or some other fancy glyph; on a different computer, however, it will likely appear as a completely different character, or nothing at all.
Your best bet is to replace the character with the nearest equivalent ASCII character, or to use an appropriate character entity. For more information on Character Encoding on the web, see Alan Flavell's excellent HTML Character Set Issues reference.
This error can also be triggered by formatting characters embedded in documents by some word processors. If you use a word processor to edit your HTML documents, be sure to use the "Save as ASCII" or similar command to save the document without formatting information.
An "id" is a unique identifier. Each time this attribute is used in a document it must have a different value. If you are using this attribute as a hook for style sheets it may be more appropriate to use classes (which group elements) than id (which are used to identify exactly one element).
This error can be triggered by:
Try to check the spelling and case of the id you are referring to.
The document type could not be determined, because the document had no correct DOCTYPE declaration. The document does not look like HTML, therefore automatic fallback could not be performed, and the document was only checked against basic markup syntax.
Learn how to add a doctype to your document
from our FAQ, or use the validator's
Document Type option to validate your document against a specific Document Type.
The construct <foo<bar> is valid in HTML (it is an example of the rather obscure “Shorttags” feature) but its use is not recommended. In most cases, this is a typo that you will want to fix. If you really want to use shorttags, be aware that they are not well implemented by browsers.
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.
The construct </foo<bar> is valid in HTML (it is an example of the rather obscure “Shorttags” feature) but its use is not recommended. In most cases, this is a typo that you will want to fix. If you really want to use shorttags, be aware that they are not well implemented by browsers.
A DOCTYPE declares the version of the language used, as well as what the root (top) element of your document will be. For example, if the top element of your document is <html>, the DOCTYPE declaration will look like: "<!DOCTYPE html".
In most cases, it is safer not to type or edit the DOCTYPE declaration at all, and preferable to let a tool include it, or copy and paste it from a trusted list of DTDs.
This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.
The construct <> is sometimes valid in HTML (it is an example of the rather obscure “Shorttags” feature) but its use is not recommended. In most cases, this is a typo that you will want to fix. If you really want to use shorttags, be aware that they are not well implemented by browsers.
The construct </> is valid in HTML (it is an example of the rather obscure “Shorttags” feature) but its use is not recommended. In most cases, this is a typo that you will want to fix. If you really want to use shorttags, be aware that they are not well implemented by browsers.
An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (;). The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs".
Entity references start with an ampersand (&) and end with a semicolon (;). If you want to use a literal ampersand in your document you must encode it as "&" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and æ are different characters.
If this error appears in some markup generated by PHP's session handling code, this article has explanations and solutions to your problem.
Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.
The checked page did not contain a document type ("DOCTYPE") declaration. The Validator has tried to validate with a fallback DTD, but this is quite likely to be incorrect and will generate a large number of incorrect error messages. It is highly recommended that you insert the proper DOCTYPE declaration in your document -- instructions for doing this are given above -- and it is necessary to have this declaration before the page can be declared to be valid.
Your document includes a DOCTYPE declaration with a public identifier (e.g. "-//W3C//DTD XHTML 1.0 Strict//EN") but no system identifier (e.g. "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"). This is authorized in HTML (based on SGML), but not in XML-based languages.
If you are using a standard XHTML document type, it is recommended to use exactly one of the DOCTYPE declarations from the recommended list on the W3C QA Website.
This may happen if you have consecutive comments but did not close one of them properly. The proper syntax for comments is <!-- my comment -->.
If you meant to include an entity that starts with "&", then you should terminate it with ";". Another reason for this error message is that you inadvertently created an entity by failing to escape an "&" character just before this text.
This is generally the sign of an ampersand that was not properly escaped for inclusion in an attribute, in a href for example. You will need to escape all instances of '&' into '&'.
This message may appear in several cases:
This error may occur when there is a mistake in how a self-closing tag is closed, e.g '.../ >'. The proper syntax is '... />' (note the position of the space).
You've included a character reference to a character that is not defined in the document type you've chosen. This is most commonly caused by numerical references to characters from vendor proprietary character repertoires. Often the culprit will be fancy or typographical quote marks from either the Windows or Macintosh character repertoires.
The solution is to reference UNICODE characters instead. A list of common characters from the Windows character repertoire and their UNICODE equivalents can be found in the document "On the use of some MS Windows characters in HTML" maintained by Jukka Korpela <jkorpela@cs.tut.fi>.
