Warnings:
The character encoding “gb2312” is not widely supported. Better interoperability may be achieved by using “UTF-8”.
Using “gbk” instead of the declared encoding “gb2312”.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “type” attribute is unnecessary for JavaScript resources.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
Errors:
Legacy encoding “gbk” used. Documents must use UTF-8.
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “text/html; charset=gb2312” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
Bad value “cache-control” for attribute “http-equiv” on element “meta”.
Bad value “bookmark” for attribute “rel” on element “link”: The string “bookmark” is not a registered keyword.
Bad value “mobile-agent” for attribute “http-equiv” on element “meta”.
Element “dl” is missing a required child element.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “font” element is obsolete. Use CSS instead.
Text not allowed in element “dl” in this context.
No “dt” element in scope but a “dt” end tag seen.
Stray end tag “span”.
No space between attributes.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
