HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in French. Consider adding “lang="fr"” (or variant) to the “html” start tag.
Errors:
Attribute “height” not allowed on element “meta” at this point.
Element “meta” is missing required attribute “content”.
Bad value ““text/javascript”” for attribute “type” on element “script”: Expected a token character but saw ““” instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
End tag “div” seen, but there were open elements.
Unclosed element “ul”.
The “itemprop” attribute was specified, but the element is not a property of any item.
