I'm working on a jQuery animation that expands the height of a 'div.panel' on mouse over and comes back to normal when the mouse is out.

The animation works for the selected 'div.panel', specially if is a '.panel.panel-small', but the problem is relative at the nearby elements that moves down from their initial location when the mouse is over the 'div.panel.panel-big'!

Here's a fiddle of my problem. Thanks in advance!
