You put a <div class="diag"> immediately after <body> and
</div><!--end div.diag--> just before </body>. Now you keep moving that
end tag up until the error line number changes. When you find a few
lines of code where the line number changes between putting the end tag
above those lines and below those lines, the problem is somewhere in
those lines.

I use <br/> and <hr/> all the time in HTML5, and it passes both my well
formed XML check and w3c validation.
In HTML5 that's also well formed XML, all tags that CAN be containers
must be <p></p> even if they contain nothing. All tags that
CANNOT be containers must be <hr/> or </br>, or at least that's what the
w3c validator tells me.
Probably most browsers are agnostic on this issue, but non-container
elements should end with slash+greater_than.
