Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad value “cleartype” for attribute “http-equiv” on element “meta”.
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”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Element “span” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Attribute “type” not allowed on element “br” at this point.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
