## What it is
Vivify is a free, MIT-licensed CSS animation library providing dozens of ready-made keyframe animation classes like fadeIn, popIn, shake, and spin. It works by including a single stylesheet and adding utility classes, with optional delay and duration modifier classes.

## Use cases
- animate elements on a webpage with css classes
- add fade in and fade out effects to html elements
- make an element shake or pulsate on hover
- add entrance animations like popIn or swoopIn to a landing page
- control animation delay and duration with utility classes
- create infinite looping css animations

## When to choose
- you want lightweight css-only animations without javascript
- you need a simple drop-in stylesheet with many animation presets
- you prefer class-based animation control with easy delay/duration tweaks

## When to avoid
- you need javascript-controlled or scroll-triggered animations
- you want physics-based or spring animations
- you need a framework-integrated animation system like framer-motion or gsap
