j'ai crée il y a peu de temps mon premier site internet avec Dreamweaver MX (http://www.webmaster-hub.com/index.php?showtopic=35454)... Cependant, après l'avoir mis en ligne, des internautes m'ont averti qu'il ne fonctionnait pas 'normalement' sous Firefox... Moi qui n'aie qu'Internet Explorer version 7, je n'ai pu m'en rendre compte lors de sa création
1. Error Line 1 column 0: no document type declaration; implying "<!DOCTYPE HTML SYSTEM>".
<html>
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.
2. Error Line 7 column 22: document type does not allow element "STYLE" here.
<style type="text/css">
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).
3. Error Line 49 column 6: 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 occured in a script section of your document, you should probably read this FAQ entry.
4. Error Line 50 column 254: document type does not allow element "BODY" here.

5. Error Line 53 column 44: there is no attribute "HEIGHT".

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.
6. Error Line 103 column 20: element "MARQUEE" undefined.
<marquee>
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:
o 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),
o by using vendor proprietary extensions such as "<spacer>" or "<marquee>" (this is usually fixed by using CSS to achieve the desired effect instead).
o by using upper-case tags in XHTML (in XHTML attributes and elements must be all lower-case.
7. Error Line 119 column 67: there is no attribute "BORDER".
