Errors:
Legacy encoding “gbk” used. Documents must use UTF-8.
The only allowed value for the “charset” attribute for the “meta” element is “utf-8”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.
Bad value “miphtml” for attribute “rel” on element “link”: The string “miphtml” is not a registered keyword.
Attribute “name” not allowed on element “div” 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.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
