About This Tool

What does this tool do?

A granular animation timeline editor. Add unlimited percentage keyframe steps (0%, 25%, 50%, 75%, 100%), assign unique CSS property values (transforms, colors, opacity, dimensions) to each step, preview the continuous loop or scrub frames, and copy formatted `@keyframes` stylesheet code, Tailwind V4, or Bootstrap markup.

When should you use it?

Use this tool for complex multi-stage animations such as bouncy notification icons, progressive progress bar pulses, sequential particle float effects, and attention-grabbing badge wobbles.
