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”.
Element “title” not allowed as child of element “head” in this context. (Suppressing further errors from this subtree.)
Attribute “arial-label” not allowed on element “a” at this point.
Attribute “enablejsapi” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
No “p” element in scope but a “p” end tag seen.
The element “footer” must not appear as a descendant of the “footer” element.
Bad value “” for attribute “value” on element “progress”: The empty string is not a valid non-negative floating point number.
Stray end tag “span”.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “button” role is unnecessary for element “button”.
Empty heading.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
