Errors:

Element “script” must not have attribute “async” unless attribute “src” is also specified.
The “charset” attribute on the “link” element is obsolete. Use an HTTP Content-Type header on the linked resource instead.
A “script” element with the “language="JavaScript"” attribute set must not have a “type” attribute whose value is not “text/javascript”.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “_blank"” not allowed on element “a” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
The “complementary” role is unnecessary for element “aside”.
