HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include more than one “meta” element with a “charset” attribute.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Bad character “<” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
End tag “p” seen, but there were open elements.
Unclosed element “a”.
Start tag “a” seen but an element of the same type was already open.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Attribute “alt” not allowed on element “a” at this point.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
