title: Import CSS from "node_modules" in Webpack
body: <p>Some third-party modules I'm using have their own CSS files. I'd like to include them in my app's one, single CSS file, which is processed by Webpack. How can CSS files under "node_modules" be imported into my CSS file?</p>
  
  <p>For example, I'm using the third-party <code>react-select</code> module, but I can't import its CSS file from <code>node_modules</code>:</p>
  
  <pre><code>@import 'react-select/dist/react-datetime.css';
  </code></pre>
  
  <p>The relevant loader in <code>webpack.config.js</code>:</p>
  
  <pre><code>  {
      test: /\.css$/,
      use: ExtractTextPlugin.extract({
        use: [
          {
            loader: 'css-loader',
            options: {
              url: false
            }
          }
        ]
      })
    }
  </code></pre>
