HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
End tag “li” seen, but there were open elements.
Unclosed element “a”.
Start tag “a” seen but an element of the same type was already open.
No “a” element in scope but a “a” end tag seen.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in English but the “html” start tag has an empty “lang” attribute. Consider using “lang="en"” (or variant) instead.
