HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “resource-type” for attribute “http-equiv” on element “meta”.
The “align” attribute on the “img” element is obsolete. Use CSS instead.
The first child “option” element of a “select” element with a “required” attribute, and without a “multiple” attribute, and without a “size” attribute whose value is greater than “1”, must have either an empty “value” attribute, or must have no text content. Consider either adding a placeholder option label, or adding a “size” attribute with a value equal to the number of “option” elements.
Duplicate ID “menu-moteur”.
Duplicate ID “menu”.
Duplicate ID “moteur-de-recherche”.
Duplicate ID “mot”.
Duplicate ID “bloc-reseaux-sociaux”.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The first occurrence of ID “menu-moteur” was here.
The first occurrence of ID “menu” was here.
The first occurrence of ID “moteur-de-recherche” was here.
The first occurrence of ID “mot” was here.
The first occurrence of ID “bloc-reseaux-sociaux” was here.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
