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.
Duplicate attribute “class”.
End tag “br”.
Attribute “alt” not allowed on element “input” at this point.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Bad value for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “list” role is unnecessary for element “ul”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
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).
