HTML markup errors and warnings
(Rescan now...)
Warnings:
The “navigation” role is unnecessary for element “nav”.
“role="none"” is not yet supported in all browsers. Consider instead either using “role="presentation"” or “role="none presentation"”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “type” attribute is unnecessary for JavaScript resources.
Errors:
Element “downloader” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “div” seen, but there were open elements.
Unclosed element “downloader”.
Element “script” must not have attribute “async” unless attribute “src” is also specified or unless attribute “type” is specified with value “module”.
