HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Attribute “itemprop” not allowed on element “meta” at this point.
The “font” element is obsolete. Use CSS instead.
Bad value “nofllow” for attribute “rel” on element “a”: The string “nofllow” is not a registered keyword.
Element “h1” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “style” 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.
Attribute “data” not allowed on element “script” at this point.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
This document appears to be written in Simplified Chinese. Consider adding “lang="zh-hans"” (or variant) to the “html” start tag.
