An illusion technique for scrolling backgrounds which allows for a finer simulation of depth in 2D graphics.

Parallax scrolling is a technique of using different rates of scrolling for multiple layers of background. The farther items in the background scroll at a slower pace than those in the foreground, which mimics the actual displacement of objects at a distance in 3D.

This tag is used for questions dealing with the implementation and common practices for using parallax scrolling in games.
