## What it is
Ramjet is a JavaScript library that makes DOM elements appear to morph into one another using smooth CSS-based animations. It clones and animates elements so transitions between different states look seamless, similar to the iOS 8 app-icon zoom effect.

## Use cases
- morph one dom element into another with a smooth animation
- create magic-move transitions between ui elements
- animate an element expanding into a modal
- make list item transitions look like they transform in place
- add ios-style zoom transitions to a web app

## When to choose
- you want element-to-element morph transitions without a full framework
- you need smooth, gpu-accelerated css animations in the browser
- you want a tiny standalone library with a simple transform api

## When to avoid
- you need a general-purpose animation engine like gsap or anime.js
- your project uses a framework with built-in transition systems
- you need actively maintained software with recent releases

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components
- domain: frontend, web-development
- platform: browser
- tags: dom-morphing, css-transitions, magic-move, element-transformation, javascript
