title: Having a fallback for a transparent background RGBA background in CSS
body: <p>I have a div over an image that I use on hover to have some kind of milky layer, which I get with <code>background-color:rgba(255,255,255,0.1)</code>.</p>
  
  <p>As I am cross browser testing my web site, I realize that rgba is not supported by IE8. So what I would like is not to have the milky layer at all when rgba is not supported. Here below what I tried as fallback:</p>
  
  <pre><code>1/ background-color:rgba(255,255,255,0.1);
  
  2/ background-color:transparent; background-color:rgba(255,255,255,0.1);
  
  3/ background-color:none; background-color:rgba(255,255,255,0.1);
  </code></pre>
  
  <p>With all three tries, I have a full blank layer over my image. How can I accomplish this?</p>
