Note: This page was created for GSAP version 2. We have since released GSAP 3 with many improvements. While it is backward compatible with most GSAP 2 features, some parts may need to be updated to work properly. Please see the GSAP 3 release notes for details. Learn how to make a simple play / pause toggle button to control any GSAP animation (tweens or timelines). Same concepts apply to toggling the reversed() state of an animation too.
