slimScroll is a small jQuery plugin that transforms any div into a scrollable area with a nice scrollbar - similar to the one Facebook and Google started using in their products recently. slimScroll doesn't occupy any visual space as it only appears on a user initiated mouse-over. User can drag the scrollbar or use mouse-wheel to change the scroll value.

jQuery('#scroll').slimScroll({
height: jQuery(window).height()+'px', //if you want whole page containing div to get scroll it's a trick only
mouseOver:true // if element you want to scroll will already hovered then make it true else no need to mention it.
});
