title: CSS3 with linear gradient for two directions
body: <p>I have a header in my website which currently use a linear gradient to move from one color to the other. This is the CSS:</p>
  
  <pre><code>#top-header {
      position: absolute;
      bottom: 0;
      left: 0;
      width: 100%;
      z-index: 99999;
      /* FF3.6+ */
      background: -webkit-gradient(linear, left top, right top, color-stop(100%, #be2e26), color-stop(20%, #be2e26), color-stop(20%, rgba(22, 22, 22, 0)), color-stop(20%, rgba(22, 22, 22, 0)));
      /* Chrome,Safari4+ */
      background: -webkit-linear-gradient(left, #be2e26 100%, #be2e26 40%, rgba(22, 22, 22, 100) 100%, rgba(22, 22, 22, 100) 100%);
      /* Chrome10+,Safari5.1+ */
      /* Opera 11.10+ */
      /* IE10+ */
      background: linear-gradient(to right, #be2e26 30%, #be2e26 20%, rgba(22, 22, 22, 0) 50%, rgba(22, 22, 22, 0) 100%);
      /* W3C */
      filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#be2e26', endColorstr='#be2e26', GradientType=1);
      /* IE6-9 */
      -webkit-transition: all 0.3s;
      transition: all 0.3s;
  } 
  </code></pre>
  
  <p>It starts from the left and slightly change the color to the right. I want to do the same thing from the right at the same time. I tried to include the following, but it keeps only one of the two lines:</p>
  
  <pre><code>background: linear-gradient(to right, #be2e26 30%, #be2e26 20%, rgba(22, 22, 22, 0) 50%, rgba(22, 22, 22, 0) 100%);
  background: linear-gradient(to left, #be2e26 30%, #be2e26 20%, rgba(22, 22, 22, 0) 50%, rgba(22, 22, 22, 0) 100%);
  </code></pre>
  
  <p>It keeps only the second. Any idea how to fix this?</p>
