css height problem

The content wrapper (called in my css: drop-shadow curls) is not expanding to fit whatever content i add. it's driving me crazy. what do i have to do to make it work? I don't want to have to define a static width, because it's going to change with every page.

here's where i'm working on it

That is because you have some floated divs inside the parent div. The floated elements are not part of the parent's overflow. To solve that, there are several workarounds. A simple one is to add a last, empty div, to clear the float

Code:

---

<div id="main">
...
<div style="clear:both"></div>
</div>

---

i changed my code around slightly and used that too, but it still isn't working >_<
