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 “type” attribute is unnecessary for JavaScript resources.
The first occurrence of ID “NavIn” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “charset” attribute on the “script” element is obsolete.
This document appears to be written in Simplified Chinese. Consider adding “lang="zh-hans"” (or variant) to the “html” start tag.
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”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “NavIn”.
The only allowed value for the “accept-charset” attribute for the “form” element is “utf-8”.
Bad value “###” for attribute “href” on element “a”: Illegal character in fragment: “#” is not allowed.
No space between attributes.
End tag “br”.
Stray end tag “span”.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
