HTML markup errors and warnings
(Rescan now...)
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The “profile” attribute on the “head” element is obsolete.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.
Bad value “cleartype” for attribute “http-equiv” on element “meta”.
Discarding unrecognized token “Home” from value of attribute “role”. Browsers ignore any token that is not a defined ARIA non-abstract role.
Bad value “logo image” for attribute “role” on element “img”.
Duplicate ID “logo-image”.
Element “div” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “banner” role is unnecessary for element “header”.
The first occurrence of ID “logo-image” was here.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
