HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode 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.
Element “input” is missing required attribute “alt”.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “center” element is obsolete. Use CSS instead.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Element “g:plusone” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No “p” element in scope but a “p” end tag seen.
Warnings:
Element name “g:plusone” cannot be represented as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
