HTML markup errors and warnings
(Rescan now...)
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
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).
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “complementary” role is unnecessary for element “aside”.
The “contentinfo” role is unnecessary for element “footer”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Errors:
Element “span” 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.
