Can I change the height of a div (not hide / show)

Can I change the height of a div (not hide / show)

Hi All,

If I have a div with a specific height:

<div id="maingraphic" style="height:200px">
</div>


Can I use jquery (perhaps .animate?) to toggle the height of that div from 200px to 450px, and then (upon a different click) back down to 200px?

Thanks very much in advance!
