Errors:
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad character “<” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Element “div” not allowed as child of element “hgroup” in this context. (Suppressing further errors from this subtree.)
Element “hgroup” is missing a required instance of one or more of the following child elements: “h1”, “h2”, “h3”, “h4”, “h5”, “h6”.
End tag “div” seen, but there were open elements.
Unclosed element “form”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
This document appears to be written in French. Consider adding “lang="fr"” (or variant) to the “html” start tag.
