(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “nav” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Stray end tag “a”.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
No “p” element in scope but a “p” end tag seen.
Duplicate ID “sidebar”.
Stray end tag “div”.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “sidebar” was here.
