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.
Attribute “alt” not allowed on element “a” at this point.
Element “fb:like” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
End tag “div” seen, but there were open elements.
Unclosed element “span”.
No “p” element in scope but a “p” end tag seen.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
Element name “fb:like” cannot be represented as XML 1.0.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
