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The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “charset” attribute on the “script” element is obsolete.
The “language” attribute on the “script” element is obsolete.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.
Bad value “text/html; charset=gb2312” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
Element “object” is missing one or more of the following attributes: “data”, “type”.
The “classid” attribute on the “object” element is obsolete. Use the “data” and “type” attributes to invoke plugins. To set a parameter with the name “classid”, use the “param” element.
The “codebase” attribute on the “object” element is obsolete. Use the “data” and “type” attributes to invoke plugins. To set a parameter with the name “codebase”, use the “param” element.
Stray end tag “embed”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “li” implied, but there were open elements.
Unclosed element “a”.
Start tag “a” seen but an element of the same type was already open.
No “a” element in scope but a “a” end tag seen.
End tag “li” seen, but there were open elements.
No space between attributes.
Stray end tag “object”.
Stray end tag “div”.
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.)
