HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Element “link” is missing one or more of the following attributes: “itemprop”, “rel”.
The “rev” attribute on the “link” element is obsolete. Use the “rel” attribute instead, with a term having the opposite meaning.
Attribute “value” not allowed on element “input” at this point.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
Stray end tag “div”.
