title: CSS @media rule in pug?
body: <p>Is it possible to apply @media rules on pug? I don't know how to adjust my pages' components when the screen size is changed.</p>
  <p>I've tried</p>
  <pre><code>@media only screen and (max-width : 320px){
      body{
        background: #FF5D50;
      }
  }
  </code></pre>
  <p>but nothing happens when I change the device on Chrome.</p>
