A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “cleartype” for attribute “http-equiv” on element “meta”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Bad value “base” for attribute “role” on element “footer”.
The “language” attribute on the “script” element is obsolete. Use the “type” attribute instead.
