EqualHeights is a simple and easy to use jQuery Plugin, which do a simple task of making equal height of all the elements you specify.
If you are having more than 1 div (boxes) in a page and you want consistency in your design, by applying the same height to all the boxes, this is the right scenario to use this plugin. You can (optionally) specify a minimum and maximum height you want the element to be. Note that if your tallest elements contain more than the maximum height worth of content, the containing element will still be resized, and a scroll bar will appear on the side of the element.
You can see a demo of this plugin here
