(Rescan now...)
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”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “ul” at this point.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “align” attribute on the “p” element is obsolete. Use CSS instead.
Bad value “” for attribute “id” on element “section”: An ID must not be the empty string.
Duplicate attribute “rel”.
Stray start tag “script”.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “banner” role is unnecessary for element “header”.
Attribute “"” is not serializable as XML 1.0.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
