The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
No space between attributes.
Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.

End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
Stray end tag “div”.
