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 “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
End tag “div” seen, but there were open elements.
Unclosed element “span”.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Element “h5” not allowed as child of element “label” in this context. (Suppressing further errors from this subtree.)

Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “banner” role is unnecessary for element “header”.
