title: CSS3, how to make my Gradient WebKit Background Transparent?
body: <p>I have the following line of CSS:</p>
  
  <pre><code>background: -webkit-gradient(linear, left top, left bottom, from(#243d63), to(#1a2638));
  </code></pre>
  
  <p>How can I make the background transparent, ie an opacity of .9, so the user can see what's under the div that has this style? Just for WebKit only concern...</p>
  
  <p>Thanks</p>
