(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.

The “navigation” role is unnecessary for element “nav”.
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “meta” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “nav” seen, but there were open elements.
Unclosed element “div”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “itemprop” attribute was specified, but the element is not a property of any item.
