Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “contentinfo” role is unnecessary for element “footer”.
This document appears to be written in English but the “html” start tag has “lang="fr-FR"”. Consider using “lang="en"” (or variant) instead.
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).
