Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
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 “action” on element “form”: Must be non-empty.
Element “div” is missing one or more of the following attributes: “role”.
Attribute “about” not allowed on element “article” at this point.
Attribute “content” not allowed on element “span” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
No “p” element in scope but a “p” end tag seen.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
The “banner” role is unnecessary for element “header”.
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).
