(Rescan now...)
Errors:
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Duplicate attribute “type”.
Stray end tag “span”.
End tag “br”.
End tag “div” seen, but there were open elements.
Unclosed element “ul”.
Stray end tag “li”.
No “li” element in scope but a “li” end tag seen.
Stray end tag “ul”.
Bad value “submit” for attribute “type” on element “a”: Subtype missing.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
The “for” attribute of the “label” element must refer to a non-hidden form control.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
Potentially bad value “copyright” for attribute “rel” on element “link”: The keyword “copyright” for the “rel” attribute should not be used. Consider using “license” instead.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
