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.
Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Bogus comment.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
End tag “section” seen, but there were open elements.
Unclosed element “div”.
Element “style” not allowed as child of element “body” 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 “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “complementary” role is unnecessary for element “aside”.
The document is not mappable to XML 1.0 due to a trailing hyphen in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
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).
