yarn add radium
# or
npm install --save radium


<Button kind="primary">Radium Button</Button>import Radium from 'radium';
import React from 'react';
import color from 'color';

class Button extends React.Component {
static propTypes = {
kind: PropTypes.oneOf(['primary', 'warning']).isRequired

render() {
// Radium extends the style attribute to accept an array. It will merge
// the styles in order. We use this feature here to apply the primary
// or warning styles depending on the value of the `kind` prop. Since its
// all just JavaScript, you can use whatever logic you want to decide which
// styles are applied (props, state, context, etc).
return (
<button style={[styles.base, styles[this.props.kind]]}>

Button = Radium(Button);

// You can create your style objects dynamically or share them for
// every instance of the component.
var styles = {
base: {
color: '#fff',

// Adding interactive state couldn't be easier! Add a special key to your
// style object (:hover, :focus, :active, or @media) with the additional rules.
':hover': {
background: color('#0074d9')

primary: {
background: '#0074D9'

warning: {
background: '#FF4136'


  • Conceptually simple extension of normal inline styles
  • Browser state styles to support :hover, :focus, and :active
  • Media queries
  • Automatic vendor prefixing
  • Keyframes animation helper
  • ES6 class and createClass support
