HTML markup errors and warnings
(Rescan now...)
Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
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.)
The “height” attribute on the “td” element is obsolete.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.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Element name “g:plusone” cannot be represented as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
