HTML markup errors and warnings
(Rescan now...)
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “type” attribute is unnecessary for JavaScript resources.
Errors:
Element “link” is missing one or more of the following attributes: “itemprop”, “property”, “rel”.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “modulepreload”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Attribute “for” not allowed on element “span” 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.
Element “xmp” not allowed as child of element “td” in this context. (Suppressing further errors from this subtree.)
