body: <p>How can I style an hr tag?</p>
  
  <pre><code>#footer hr
  {
      background-image: -moz-linear-gradient(left, rgba(0,0,0,0), rgba(0,0,0,0.75), rgba(0,0,0,0)); 
  }
  </code></pre>
  
  <p>This doesn't work in firefox. I even tried <code>background:</code>, but that didn't work. Is there some other way to make it work? </p>
