引入css 在src下创建了两个文件夹，components文件夹用来存放各个组件，css文件夹用来存放css文件。
// style.css
.red-font{
color: #f00;
font-size:20px;
}
// cssDemo.tsx
import React from 'react';
import '../css/style.css'
export default class CssDemo extends React.Component<any, any> {
render() {
return <div className="red-font">
red font
</div>
}
}
config webpack
test: /\.css$/,
use:[
'style-loader',
'css-loader'
]
install css
npm install -D style-loader css-loader
在你的入口文件引入CssDemo渲染即可
import React from 'react';
import ReactDOM from 'react-dom';
import CssDemo from './components/cssDemo';
const render = () => {
ReactDOM.render(
<CssDemo/>,
document.querySelector('#app')
)
}
render();
