HTML markup errors and warnings
(Rescan now...)
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The “charset” attribute on the “script” element is obsolete.
The “type” attribute is unnecessary for JavaScript resources.
The “language” attribute on the “script” element is obsolete.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The “border” attribute is obsolete.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.
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”.
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.)
Bad value “mobile-agent” for attribute “http-equiv” on element “meta”.
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The “font” element is obsolete.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.
Stray end tag “div”.
