Errors:
The “profile” attribute on the “head” element is obsolete.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 “” for attribute “href” on element “link”: Must be non-empty.
Bad value for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Bad value “none” for attribute “media” on element “link”: Media query ended prematurely.
Duplicate ID “custom-google-fonts-css”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
