Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Bad value “cleartype” for attribute “http-equiv” on element “meta”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Attribute “disabled” not allowed on element “a” at this point.
The element “header” must not appear as a descendant of the “header” element.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “” for attribute “size” on element “input”: The empty string is not a valid positive integer.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “itemname” not allowed on element “div” at this point.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “banner” role is unnecessary for element “header”.
The “date” input type is not supported in all browsers. Please be sure to test, and consider using a polyfill.
The “contentinfo” role is unnecessary for element “footer”.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
