HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
Duplicate ID “logo”.
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
End tag “div” seen, but there were open elements.
Unclosed element “strong”.
Element “div” not allowed as child of element “strong” in this context. (Suppressing further errors from this subtree.)
Unclosed element “ul”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
End tag for “body” seen, but there were unclosed elements.
Warnings:
The first occurrence of ID “logo” was here.
Empty heading.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
