HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value ““author”” for attribute “rel” on element “link”: The string ““author”” is not a registered keyword.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Attribute “href” not allowed on element “div” at this point.
End tag “div” seen, but there were open elements.
Unclosed element “a”.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
