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”.
