npm install reactcss --save 

Define a default styles for your elements:

import reactCSS from 'reactcss' const styles = reactCSS({ 'default': { card: { background: this.props.background, boxShadow: '0 2px 4px rgba(0,0,0,.15)', }, }, })

Pass style definitions via inline styles:

<div style={ styles.card } />

Activate additional classes by passing down objects as additional parameters to reactCSS:

const styles = reactCSS({ 'default': { card: { background: '#fff', boxShadow: '0 2px 4px rgba(0,0,0,.15)', }, }, 'zIndex-2': { card: { boxShadow: '0 4px 8px rgba(0,0,0,.15)', }, }, }, { 'zIndex-2': props.zIndex === 2, })
