Problème html sur www.nepaldreamtea.com

Bonjour,

Sur mon site www.nepaldreamtea.com, j'ai plein d'erreurs avec http://validator.aborla.net du type :

4: <meta charset="utf-8">
<meta> lacks "content" attribute
<meta> proprietary attribute "charset"
<input> proprietary attribute "placeholder"
<a> proprietary attribute "data-container"
<a> proprietary attribute "data-container"
<a> proprietary attribute "data-lang"

Y en a plein du même type d'erreurs; quelqu'un sait de quoi il s'agit ?

Avec w3c , les erreurs sont :
Error: The align attribute on the div element is obsolete. Use CSS instead.

Il y a des erreurs de plusieurs types :
par exemple le site utilise des attributs obsolètes comme align="center", qui doivent être remplacés en CSS par text-align: center.
Autre problème, des balises obsolètes aussi, comme la meta keywords, ou inutiles comme la meta robots all.
S’ensuivent d’autres nombreuses erreurs de structure, qui apparemment sont dues au générateur de code utilisé.
Dans un cas pareil, j’essayerais d’utiliser un autre générateur qui me crée pas de balises et d’attributs obsolètes (plus facile à dire qu’à faire je le sais bien)
Mais attendez néanmoins des réponses d’autres personnes certainement plus qualifiées que moi...
