style-components是针对react写的一套css in js框架，简单来讲就是在js中写css。相对于与预处理器(sass、less)的好处是，css in js使用的是js语法，不用重新再学习新技术，也不会多一道编译步骤。无疑会加快网页速度。如果有sass或less的开发经验，几分钟就可以学会style-components。  

styled-components与React（针对web）和React Native兼容。

安装

npm install styled-components@beta

例子

import React from 'react';

import styled from 'styled-components';

// Create a <Title> react component that renders an <h1> which is
// centered, palevioletred and sized at 1.5em
const Title = styled.h1`
  font-size: 1.5em;
  text-align: center;
  color: palevioletred;
`;

// Create a <Wrapper> react component that renders a <section> with
// some padding and a papayawhip background
const Wrapper = styled.section`
  padding: 4em;
  background: papayawhip;
`;

// Use them like any other React component – except they're styled!
<Wrapper>
  <Title>Hello World, this is my first styled component!</Title>
</Wrapper>
