Errors:
A “charset” attribute on a “meta” element found after the first 1024 bytes.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad value “” for attribute “target” on element “form”: Browsing context name must be at least one character long.
Attribute “alt” not allowed on element “source” at this point.
Element “img” is missing required attribute “src”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
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).
The “contentinfo” role is unnecessary for element “footer”.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
