HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Element “appsettings” not allowed as child of element “body” 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 “appsettings” seen, but there were open elements.
Unclosed element “add”.
Attribute “src” not allowed on element “span” at this point.
Warnings:
The “document” role is unnecessary for element “body”.
The “navigation” role is unnecessary for element “nav”.
The “banner” role is unnecessary for element “header”.
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.
