HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. 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Using the “meta” element to specify the document-wide default language is obsolete.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.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
The “rev” attribute on the “link” element is obsolete. Use the “rel” attribute instead, with a term having the opposite meaning.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “subcate”.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Warnings:
The first occurrence of ID “subcate” was here.
