HTML markup errors and warnings
(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.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The element “label” must not appear as a descendant of the “a” element.
Bad value “navigation” for attribute “role” on element “ul”.
An element with “role=menuitem” must be contained in, or owned by, an element with “role=menubar” or “role=menu”.
Element “footer” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
