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 “type” attribute is unnecessary for JavaScript resources.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “charset” attribute on the “script” element is obsolete.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
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”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “form” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “center” element is obsolete. Use CSS instead.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “div” seen, but there were open elements.
Unclosed element “ul”.
The “font” element is obsolete. Use CSS instead.
Stray end tag “a”.
Element “dl” is missing a required child element.
The only allowed value for the “charset” attribute for the “script” element is “utf-8”. (But the attribute is not needed and should be omitted altogether.)
Attribute “data” not allowed on element “script” at this point.
