title: Why isn't box-shadow working?
body: <p>I can't seem to get box-shadow to work for my div element with the following CSS code:</p>
  
  <pre><code>#header {
  background-color: #B89E70;
  top: 0;
  left: 0;
  width: 100%;
  height: 5%;
  position: fixed;
  box-shadow: 0px, 20px, 5px, rgba(0, 0, 0, 0.7);
  
  
  font-family: arial;
  text-align: center;
  }
  </code></pre>
  
  <p>I'm using Chrome. Any ideas of what I might've missed?</p>
