I am trying to get a div on my page to roll up in vertical size from 250 pixels tall to about 50 when a button is clicked. I've tried to write a script to do this but haven't had any luck. I can make it change size easily enough, but I can't seem to get the smooth change from 250 to 50... it just jumps to that height. I've looked around and can't seem to find it, so I'm hoping someone here has one. Thanks!
