Errors:
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.
End tag “p” seen, but there were open elements.
Unclosed element “span”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “alt” not allowed on element “input” at this point.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Warnings:
The “navigation” role is unnecessary for element “nav”.
The “banner” role is unnecessary for element “header”.
The “article” role is unnecessary for element “article”.
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).
