Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “CACHE-CONTROL” for attribute “http-equiv” on element “meta”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “g:plusone” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “border” attribute on the “table” element is obsolete. Use CSS instead.
The “width” attribute on the “td” element is obsolete. Use CSS instead.
Bad character “ ” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “allowtransparency” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
Element name “g:plusone” cannot be represented as XML 1.0.
