HTML markup errors and warnings
(Rescan now...)
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”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “type” attribute for the “style” element is not needed and should be omitted.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
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.
