(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.
Attribute “aalt” not allowed on element “img” 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.
Duplicate ID “cssmenu”.
The string following “&” was interpreted as a character reference. (“&” probably should have been escaped as “&”.)
Attribute “loop” not allowed on element “a” at this point.
Attribute “autoplay” not allowed on element “a” at this point.
Attribute “alt” not allowed on element “a” at this point.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “cssmenu” was here.
The “main” role is unnecessary for element “main”.
