HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “popover” for attribute “rel” on element “a”: The string “popover” is not a registered keyword.
Bad character “<” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Element “img” is missing required attribute “src”.
Stray start tag “script”.
The “for” attribute of the “label” element must refer to a non-hidden form control.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in Simplified Chinese. Consider adding “lang="zh-hans"” (or variant) to the “html” start tag.
