Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Attribute “baidusug” not allowed on element “input” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “data” not allowed on element “li” at this point.
Attribute “data” not allowed on element “ul” at this point.
Start tag “a” seen but an element of the same type was already open.
The “font” element is obsolete. Use CSS instead.
Stray end tag “a”.
Attribute “data” not allowed on element “a” at this point.
Attribute “data” not allowed on element “div” at this point.
Bad character “驯” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Attribute “data” not allowed on element “h3” at this point.
Stray end tag “div”.
The only allowed value for the “charset” attribute for the “script” element is “utf-8”. (But the attribute is not needed and should be omitted altogether.)
Warnings:
The “border” attribute is obsolete.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The “language” attribute on the “script” element is obsolete.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.
The “charset” attribute on the “script” element is obsolete.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
