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.
Bad value “25px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Bad value “25px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Attribute “aria-has-popup” not allowed on element “a” at this point.
No “p” element in scope but a “p” end tag seen.
The “for” attribute of the “label” element must refer to a non-hidden form control.
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.
