## What it is
Animate.css is a cross-browser CSS library providing dozens of ready-made animation classes like fades, bounces, and attention seekers. Developers add animations by simply including a stylesheet and applying class names to HTML elements.

## Use cases
- animate elements on a webpage with css classes
- add fade-in and bounce effects to a landing page
- cross-browser css keyframe animations without writing keyframes
- respect prefers-reduced-motion for accessibility
- animate modals and tooltips on entrance and exit

## When to choose
- you want quick, dependency-free CSS animations via class names
- you need broad browser support and reduced-motion accessibility out of the box
- you prefer a stylesheet over a JavaScript animation library

## When to avoid
- you need complex, sequenced, or physics-based animations
- you require per-frame JavaScript control or scroll-linked animation
- your project disallows the Hippocratic License

- function: animation, css-framework, ui-components, accessibility
- domain: web-development, frontend, web-design
