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The “language” attribute on the “script” element is obsolete.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The “border” attribute is obsolete.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.

The “charset” attribute on the “script” element is obsolete.

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

The “type” attribute is unnecessary for JavaScript resources.

The first occurrence of ID “img_shd” was here.

The first occurrence of ID “moment_p” was here.

The first occurrence of ID “moment” was here.

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.

Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.

Bad value “text/html; charset=gb2312” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.

Attribute “height” not allowed on element “table” at this point.

The “align” attribute on the “table” element is obsolete.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

The “width” attribute on the “table” element is obsolete.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