A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “” for attribute “media” on element “link”: Media query ended prematurely.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Attribute “aria-role” not allowed on element “a” at this point.
Element “style” not allowed as child of element “li” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
