HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “https://www.w3.org/1999/xhtml” for the attribute “xmlns” (only “http://www.w3.org/1999/xhtml” permitted here).
Attribute “https-equiv” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “http-equiv”, “itemprop”, “name”, “property”.
The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.
Element “hr” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
