(Rescan now...)

Warnings:

The “type” attribute is unnecessary for JavaScript resources.

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

The “language” attribute on the “script” element is obsolete. You can safely omit it.

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.

Attribute “<” is not serializable as XML 1.0.

The “charset” attribute on the “script” element is obsolete.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.

Errors:

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

No “li” element in scope but a “li” end tag seen.

The “center” element is obsolete. Use CSS instead.

Stray end tag “script”.

Stray end tag “section”.

Attribute “f” not allowed on element “a” at this point.

Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.

Attribute “<” not allowed on element “span” at this point.

Attribute “section” not allowed on element “span” at this point.

End tag “div” seen, but there were open elements.

Unclosed element “span”.

Unclosed element “section”.
