Errors:
The “profile” attribute on the “head” element is obsolete.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 “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “” for attribute “src” on element “video”: Must be non-empty.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “div” seen, but there were open elements.
Unclosed element “section”.

Stray end tag “div”.
Bad value “footer” for attribute “role” on element “footer”.
Warnings:
