Title: Closed <div id="container"> tag

It looks like the closing tag for the container div is missing. Modern browsers should figure it out fine, but it doesn't validate. (I didn't indent everything to match since I got the impression that the author wanted to avoid extra indentation. -- just wanted to close the tag to keep that from throwing a validation error.)
