(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Stray end tag “a”.
The “sizes” attribute may be specified only if the “srcset” attribute is also present.
Attribute “counter-responsv-wrap-2013” not allowed on element “div” at this point.
Attribute “counter-responsv-wrap-8362” not allowed on element “div” at this point.
Attribute “counter-responsv-wrap-7323” not allowed on element “div” at this point.
Attribute “counter-responsv-wrap-7820” not allowed on element “div” at this point.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “banner” role is unnecessary for element “header”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
