Emotion is a performant and flexible CSS-in-JS library. Building on many other CSS-in-JS libraries, it allows you to style apps quickly with string or object styles. It has predictable composition to avoid specificity issues with CSS. With source maps and labels, Emotion has a great developer experience and great performance with heavy caching in production.

Quick Start

Get up and running with a single import.

npm install --save emotion
import { css } from 'emotion'

const app = document.getElementById('root')
const myStyle = css`
  color: rebeccapurple;

React with Optional Babel Plugin

npm install --save emotion react-emotion babel-plugin-emotion

Note: use preact-emotion in place of react-emotion if using Preact

import styled, { css } from 'react-emotion'

const Container = styled('div')`
  background: #333;
const myStyle = css`
  color: rebeccapurple;
const app = () => (
    <p className={myStyle}>Hello World</p>
