(Rescan now...)
Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Stray doctype.
Stray start tag “html”.
Cannot recover after last error. Any further errors will be ignored.
