CSS Animation Generator

Generate keyframe animations — fade, slide, bounce, pulse, spin and shake.

To generate a CSS animation, pick an effect and adjust the duration, easing and repeat count. The preview loops continuously so you can judge the motion. Animating only transform and opacity keeps the animation on the compositor and off the main thread.

Frequently asked questions

Which properties are safe to animate?

transform and opacity. Both are handled by the compositor without triggering layout or paint, so they stay smooth at 60fps. Animating width, height, top or left forces layout recalculation on every frame.

Should I respect reduced-motion preferences?

Yes. Some people experience nausea or vertigo from motion. Wrap decorative animation in @media (prefers-reduced-motion: no-preference) so it only runs for users who have not asked for less movement.
