Errors:
Legacy 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.
The “version” attribute on the “html” element is obsolete. You can safely omit it.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Duplicate ID “nav”.
Bad value “navigation” for attribute “role” on element “ul”.
Bad value “” for attribute “name” on element “input”: Must not be empty.
No “p” element in scope but a “p” end tag seen.
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Element “bottom” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
Attribute “href” without an explicit value seen. The attribute may be dropped by IE7.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “nav” was here.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “complementary” role is unnecessary for element “aside”.
The “contentinfo” role is unnecessary for element “footer”.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
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).
