SpotlightJS shows a spotlight over a Web page. It can create a transparent canvas on the top of the Web page with a dark area and a light rounded spot area which make the content below it appear as if it highlighted by a spotlight.

Callback functions may be invoked when the user drags the mouse over or clicks in the spotlight or the canvas area, as well when the animation starts and ends.
