HTML markup errors and warnings
(Rescan now...)
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
Attribute “xmlns” is not serializable as XML 1.0.
The “main” role is unnecessary for element “main”.
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).
The first occurrence of ID “ad-header” was here.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “contentinfo” role is unnecessary for element “footer”.
The “type” attribute is unnecessary for JavaScript resources.
Errors:
Bad value “https://www.w3.org/2000/svg” for the attribute “xmlns” (only “http://www.w3.org/2000/svg” permitted here).
No “p” element in scope but a “p” end tag seen.
Duplicate ID “ad-header”.
Attribute “loading” not allowed on element “img” at this point.
The “center” element is obsolete. Use CSS instead.
