Scale div vertically until all content is shown?

I have a div with a set height of 200, and sometimes there's enough content inside to have to scroll. Is there any way to be able to scale/grow the div until there's no overflow in Scriptaculous?

Edit: I looked at the wiki, especially at Effect.Scale (which seems like the one I want) but I couldn't find a way to do what I'd like.

• Use CSS?

  /*In non-IE css:*/
  .myclass {
  min-height: 270px;
  }
  
  /*In css for IE:*/
  .myclass {
  height: expression(this.scrollHeight < 270? "270px" : "auto" );
  }
