Bonjour voila j'ai réalisé un Chat et je voudrai le validé W3C mais il y quelques erreurs que je ne comprend pas
Je vous explique rapidement comment je l'ai réalisé afin que vous puissiez plus facilement m'aider :
Donc un fichier frame.html qui a une frame pour les messages et une frame pour les commandes
fichier message.php qui va rechercher toutes les x seconde dans la base si il y a de nouveaux messages et les affiches si oui
fichier commande.php qui contient toutes les commandes pour saisir le messages, modifier la couleur de la police etc...
le lien vers la page : http://forzaitalia.ath.cx en bas a gauche Mini Tchat
Merci de votre aide ...

Below are the results of checking this document for XML well-formedness and validity.
1. Error Line 11 column 18: there is no attribute "rows".
<Frameset rows="50%,40%">
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.
2. Error Line 11 column 27: element "Frameset" undefined.
<Frameset rows="50%,40%">
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.
3. Error Line 12 column 16: there is no attribute "name".
<Frame name="messages" src="Tchat_messages.php" class="Messages" />
4. Error Line 12 column 31: there is no attribute "src".
<Frame name="messages" src="Tchat_messages.php" class="Messages" />
5. Error Line 12 column 58: there is no attribute "class".
<Frame name="messages" src="Tchat_messages.php" class="Messages" />
6. Error Line 12 column 71: element "Frame" undefined.
..." src="Tchat_messages.php" class="Messages" />
7. Error Line 13 column 63: element "Frame" undefined.
...e name="pied-page" src="Tchat.php" class="Pied-page"/>
8. Error Line 19 column 6: end tag for "html" which is not finished.
</html>
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, <head> generally requires a <title>, lists (ul, ol, dl) require list items (li, or dt, dd), and so on.
