Errors:
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Bad value “encoding” for attribute “http-equiv” on element “meta”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Attribute “ontouchstart” not allowed on element “a” at this point.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Bad value for attribute “src” on element “iframe”: Tab, new line or carriage return found.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
The “banner” role is unnecessary for element “header”.
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).
