Attribute “env” not allowed on element “html” at this point.
Bad value “x-dns-prefetch-control” for attribute “http-equiv” on element “meta”.

Attribute “ontouchstart” not allowed on element “body” at this point.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Element “img” is missing required attribute “src”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
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).
