Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
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.
Bad value “cleartype” for attribute “http-equiv” on element “meta”.
Attribute “role” not allowed on element “label” at this point.
Attribute “type” not allowed on element “form” at this point.
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “container"” not allowed on element “header” at this point.
Stray end tag “div”.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
Attribute “aria-hidden” is unnecessary for elements that have attribute “hidden”.
The “main” role is unnecessary for element “main”.
Attribute “container"” is not serializable as XML 1.0.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
