# Letter Swap

> A text component that swaps the letters vertically on hover.  There are two types of animations available for this component: 1) Forward animation — plays the animation timeline once forward, when you hover over the text. 2) Ping Pong animation — plays the animation timeline in a ping pong fashion. It plays once forward when you hover over the text, and once in the opposite direction when you hover away from the text.
