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.)
Obsolete doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “td” seen, but there were open elements.
Unclosed element “div”.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
