HTML markup errors and warnings
(Rescan now...)
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Element “script” must not have attribute “async” unless attribute “src” is also specified or unless attribute “type” is specified with value “module”.
Element “a” not allowed as child of element “time” in this context. (Suppressing further errors from this subtree.)
The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.
Bad value “empty” for attribute “rel” on element “a”: The string “empty” is not a registered keyword.
The element “header” must not appear as a descendant of the “footer” element.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “form” role is unnecessary for element “form”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Empty heading.
