Errors:
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.
Element “img” is missing required attribute “src”.
Bad value “presentation” for attribute “role” on element “video”.
Attribute “playsinline” not allowed on element “source” at this point.
Element “source” is missing required attribute “src”.
Duplicate attribute “src”.
Attribute “unused-src” not allowed on element “img” at this point.
Bad value “auto” for attribute “width” on element “img”: Expected a digit but saw “a” instead.
Duplicate attribute “class”.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
The “main” role is unnecessary for element “main”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
