Errors

A “charset” attribute on a “meta” element found after the first 1024 bytes.

Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Warnings

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).

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.

The “contentinfo” role is unnecessary for element “footer”.
