HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “article” role is unnecessary for element “article”.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “main” role is unnecessary for element “main”.
The “button” role is unnecessary for element “button”.
Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “revision” for attribute “rel” on element “link”: The string “revision” is not a registered keyword.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
