HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value “” for attribute “href” on element “link”: Must be non-empty.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Stray doctype.
Attribute “xmlns:serif” not allowed here.
Duplicate attribute “id”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Element “p” not allowed as child of element “time” in this context. (Suppressing further errors from this subtree.)
End tag “div” seen, but there were open elements.
Unclosed element “time”.
No “p” element in scope but a “p” end tag seen.
Warnings:
The “banner” role is unnecessary for element “header”.
Attribute with the local name “xmlns:serif” is not serializable as XML 1.0.
The “navigation” role is unnecessary for element “nav”.
The “contentinfo” role is unnecessary for element “footer”.
