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.
Element “title” not allowed as child of element “head” in this context. (Suppressing further errors from this subtree.)
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
End tag “span” seen, but there were open elements.
Unclosed element “a”.
End tag “div” seen, but there were open elements.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
