Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “application/xhtml+xml; charset=UTF-8” for attribute “content” on element “meta”: The legacy encoding declaration did not start with “text/html;”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “projection,screen” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Element “legend” not allowed as child of element “fieldset” in this context. (Suppressing further errors from this subtree.)
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
The value of the “for” attribute of the “label” element must be the ID of a non-hidden form control.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “navigation” role is unnecessary for element “nav”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
