Warnings:

The “main” role is unnecessary for element “main”.

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.

Errors:

Element “img” is missing required attribute “src”.

The “sizes” attribute may be specified only if the “srcset” attribute is also present.

Element “figcaption” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)

Attribute “href” not allowed on element “button” at this point.

The element “button” must not appear as a descendant of the “a” element.

End tag “main” seen, but there were open elements.

Unclosed element “section”.
