title: Linking css in twig
body: <p>I'm trying to link css in my twig template. But it is not working.
  I have used following:</p>
  
  <pre><code>&lt;link href="../../vendor/style.css" rel="stylesheet" type="text/css"&gt;
  </code></pre>
  
  <p>But it is not working.
  Can anyone tell me what should i do? I've tried using asset and url functions, but it gives function not found exception.</p>
