title: css to stylus scrollbar issue
body: <p>I'm having difficulty translating some css to stylus. In my html/css tests it works absolutely fine, but when I try to rewrite it in jade and stylus I'm having some issues with proper syntax. For context I'm making a custom scrollbar.
  Here's the css that I'm trying to change:</p>
  
  <pre><code>body::-webkit-scrollbar {
      width: 12px;
      background: rgba(0,0,255,1);
  }
  
  body::-webkit-scrollbar-track {
      -webkit-box-shadow: inset 0 0 2px rgba(255,0,0,1);
  }
  
  body::-webkit-scrollbar-thumb {
      background-color: cornflowerblue;
  }
  </code></pre>
  
  <p>Essentially the <code>body::-webkit-scrollbar</code>etc. lines, how would I change that over to working stylus?</p>
