Need your HTML code as well, but I can suggest that you add a position:relative; to your #container. By the way, you've got way too many ambiguous pronouns in your explanation.
"it goes over it and it wont expand the div tag".
Not sure who is "it". ?:|

please give your html page code we can solve your problem

without looking at the css,
zero should have no dimension $0 = 0px = 0 apples = 0em = 0% = 0
zero, as 0(dimension), throws everything into quirks mode, quirks mode causes unreasonable failures
examine your css to find any 0px 0em 0% 0pt and change them to just 0
what is the "specific height" at which failure occurs

**edit
had a look, there are a few, may not be the cause, but removing unpredicatables helps
