Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “gb2312” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=gb2312” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
Attribute “http-equiv” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “font” element is obsolete. Use CSS instead.
Attribute “flag” not allowed on element “li” at this point.
Duplicate attribute “style”.
Bad value “” for attribute “name” on element “input”: Must not be empty.
Element “input” with attribute “type” whose value is “button” must have non-empty attribute “value”.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Stray end tag “div”.
Element “dl” is missing a required instance of child element “dd”.
Bad value “” for attribute “width” on element “img”: The empty string is not a valid non-negative integer.
Bad value “” for attribute “height” on element “img”: The empty string is not a valid non-negative integer.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The element “input” must not appear as a descendant of the “a” element.
Element “dd” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate attribute “type”.
Stray end tag “input”.
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “_self"” not allowed on element “a” at this point.
CSS: “target”: Parse Error.
Stray start tag “script”.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Attribute “_self"” is not serializable as XML 1.0.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
