HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
End tag “p” seen, but there were open elements.
Unclosed element “code”.
Element “style” not allowed as child of element “code” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “code” in this context. (Suppressing further errors from this subtree.)
End tag “code” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “banner” role is unnecessary for element “header”.
Empty heading.
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “main” role is unnecessary for element “main”.
The “complementary” role is unnecessary for element “aside”.
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).
The “contentinfo” role is unnecessary for element “footer”.
