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.
Bad value “”image/x-icon”” for attribute “type” on element “link”: Expected a token character but saw “”” instead.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Bad value “tel:+34 93 221 10 00” for attribute “href” on element “a”: Illegal character in scheme data: space is not allowed.
End tag “header” seen, but there were open elements.
Unclosed element “div”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
No “p” element in scope but a “p” end tag seen.
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
Text run is not in Unicode Normalization Form C.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
