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.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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”.
Bad value “mobile-agent” for attribute “http-equiv” on element “meta”.
Element “p” not allowed as child of element “a” 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 “ul” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
