The “profile” attribute on the “head” element is obsolete.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.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “h4”.
Duplicate ID “search-form”.
Duplicate ID “edit-basic”.
Duplicate ID “edit-keys”.
Duplicate ID “edit-submit”.
Bad value “banner” for attribute “role” on element “nav”.
