HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “” for attribute “media” on element “link”: Media query ended prematurely.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “value""” not allowed on element “input” at this point.
The element “button” must not appear as a descendant of the “a” element.
Bad value “true” for attribute “async” on element “script”.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Attribute “value""” is not serializable as XML 1.0.
This document appears to be written in French but the “html” start tag has “lang="en"”. Consider using “lang="fr"” (or variant) instead.
