class-props

React component for quickly applying multiple classNames – great for libraries like Tachyons and Basscss

npm i class-props

import React from 'react'
import Base from 'class-props'

const App = props => (
  <React.Fragment>
    <link ref='stylesheet' href='https://unpkg.com/basscss@8.0.2/css/basscss.min.css' />
    <Base px3 py4>
      <Base is='h1' h1>
        Hello
      </Base>
    </Base>
  </React.Fragment>
)

// Creating a style component
const Heading = props =>
  <Base
    is='h2'
    {...props}
    h2
    mt3
    mb2
  />
