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The “language” attribute on the “script” element is obsolete.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The “border” attribute is obsolete.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.
The only allowed value for the “charset” attribute for the “meta” element is “utf-8”.
Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.
Bad value “mobile-agent” for attribute “http-equiv” on element “meta”.
Bad value “only screen and(max-width:640px)” for attribute “media” on element “link”: Expected a letter or whitespace but saw “(” instead.
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.
No “p” element in scope but a “p” end tag seen.
Bad value “true” for attribute “border” on element “img”: Only “0” is a permitted zero literal.
The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.
