(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “banner” role is unnecessary for element “header”.
The “article” role is unnecessary for element “article”.
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”.
Errors:
A “charset” attribute on a “meta” element found after the first 1024 bytes.
