react-css-transition is an easy way to perform CSS transitions and animations when a React Componenet enters or leaves the DOM.

Demo & Examples

Live demo:

To build the examples locally, run:

npm install
npm start

Then open localhost:8000 in a browser.


The easiest way to use react-css-transition is to install it from NPM and include it in your own React build process (using Browserify, Webpack, etc).

You can also use the standalone build by including dist/react-css-transition.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.

npm install react-css-transition --save


var ReactCssTransition = require('react-css-transition');

<ReactCssTransition className='example-box'
  options={{ onClick: this.togglePopup.bind(this) }} > Click! </ReactCssTransition>


Property Type Description Default
visible bool Initialize state True
className string custom class name
enterTimeout number the number of milliseconds 500
leaveTimeout number the number of milliseconds 500
options object other props
onEnterTransitionStart function called at the start of 'enter transition'
onEnterTransitionEnd function called at the end of 'enter transition'
onLeaveTransitionStart function called at the start of 'leave transition'
onLeaveTransitionEnd function called at the end of 'leave transition'


In css, className according to transition state is defined as follows. when className is 'example',

.example-box {
  -webkit-transition: opacity 1000ms ease;
  -moz-transition: opacity 1000ms ease;
  -ms-transition: opacity 1000ms ease;
  -o-transition: opacity 1000ms ease;
  transition: opacity 1000ms ease;

.example-box.enter {
  opacity: 1;
.example-box.leave {
  opacity: 0;

Development (src, lib and the build process)

NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.

To build, watch and serve the examples (which will also watch the component source), run npm start. If you just want to watch changes to src and rebuild lib, run npm run watch (this is useful if you are working with npm link).
