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.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “handheld” for attribute “media” on element “link”: Deprecated media type “handheld”. For guidance, see the Media Types section in the current Media Queries specification.
Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Duplicate ID “menu”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “document” role is unnecessary for element “body”.
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “menu” was here.
The “contentinfo” role is unnecessary for element “footer”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
