(Rescan now...)
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad value “EXPIRES” for attribute “http-equiv” on element “meta”.
Element “object” is missing one or more of the following attributes: “data”, “type”.
The element “a” must not appear as a descendant of the “a” element.
Attribute “taeget” not allowed on element “a” at this point.
Element “nobr” not allowed as child of element “div” 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 “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “main” role is unnecessary for element “main”.
Empty heading.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
