[jQuery] Simple/obvious way to reveal items clipped by overflow:hidden ?

[jQuery] Simple/obvious way to reveal items clipped by overflow:hidden ?


Let's say I have a div with a CSS height of 200px, with
overflow:hidden, and so there's content clipped inside it.
Is there any way to have .hover() make that div expand down to reveal
the internal content, without having to manually specify the target
height?
Since overflow:auto produces proportional scrollbars, I have the
impression that the browser /does/ know this number somehow, but I
have no idea how to get at it.
