HTML markup errors and warnings
(Rescan now...)
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “navigation” role is unnecessary for element “nav”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Empty heading.
Errors:
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
The element “a” must not appear as a descendant of the “button” element.
Duplicate attribute “alt”.
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.
Bad value for attribute “src” on element “iframe”: Illegal character in query: space is not allowed.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
End tag for “body” seen, but there were unclosed elements.
