## What it is
Bounce.js is a JavaScript library and web tool for generating CSS3 keyframe animations using components like scale, rotate, translate, and skew. It can output static CSS keyframes or generate animations dynamically in the browser.

## Use cases
- generate css keyframe animations for web elements
- create bounce and sway easing effects without writing css by hand
- dynamically apply animations to dom elements at runtime
- build playful ui animations like pop-in and rotation effects
- export static css animations from a visual tool

## When to avoid
- you need complex timeline or scroll-based animations
- you want actively maintained software with recent updates
- you need physics-based or canvas/webgl animation
