HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “script” must not have attribute “async” unless attribute “src” is also specified.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “center” element is obsolete. Use CSS instead.
End tag “div” seen, but there were open elements.
Unclosed element “section”.
Stray end tag “section”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
