[débutante] problème de validation des méta-tags

Bonjour à tous,
je viens de terminer mes pages en xhtml/css et je rencontre un problème avec les méta-tag.
Je n'arrive pas à les valider sur w3.org
Quelqu'un pourrait-il m'aider et me dire ce que je dois changer car je m'y perds.

voici ce que j'ai écrit dans <head>:

Par contre voici les erreurs que w3.org me signalent.Que puis-je donc changer ???

Citation:

Error Line 4 column 20: there is no attribute "http-equiv".
<META http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
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.

You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".

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.

Merci beaucoup pour votre aide

Alors déjà il y a une erreur au mot accueil.

Sinon essaies déjà de fermer toutes tes balises de meta en mettant /> à la place de >.

Ensuite en cherchant sur le site de W3 j'ai trouvé ceci en entête de leurs pages
Code:

1 2 3 4 5 <?xml version="1.0" encoding="iso-8859-1"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head profile="http://www.w3.org/2002/12/wg">
Tu peux toujours essayer.

même remarque... déjà, fermet les balises meta-tag. Ensuite, tant qu'a être complet, rajouter le doctype

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

le <?xml.... ?> n'est pas nécessaire.

merci pour votre aide mais j'ai trouvé un générateur de méta-tags qui a résolu le problème en surplus de vos renseignements

Je ferais d'ailleurs aussi bien de revoir également mon orthographe (ACCUEIL) :lol:
