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The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

The “language” attribute on the “script” element is obsolete. You can safely omit it.

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 “bookmark” for attribute “rel” on element “link”: The string “bookmark” is not a registered keyword.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

The “align” attribute on the “table” element is obsolete. Use CSS instead.

The “cellpadding” attribute on the “table” element is obsolete. Use CSS instead.

The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.

Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
