Build smooth CSS animations on a visual timeline. Shape every keyframe, tune playback, preview the motion live and copy clean CSS when it feels just right.
Experiment with animation ideas visually, then move straight from the timeline to standards-based CSS.
Adjust position, movement, scale, rotation, opacity, color and corner radius at any point.
Drag the playhead, pause on a detail and inspect exactly how the animation changes.
Get both the @keyframes rule and the matching animation declaration.
Choose a preset such as Float, Bounce or Slide in, or build your motion from scratch. Select a marker on the timeline and adjust that keyframe’s transform and appearance controls. Add more keyframes wherever the animation needs an extra beat.
Use the playback buttons to pause, replay or jump to the end, and drag across the timeline to inspect the in-between motion. Fine-tune duration, timing function, iteration count, direction and fill mode. When the preview feels right, select Copy CSS to copy the complete animation into your stylesheet. Everything runs locally in your browser.
