title: Css opacity and elements in div
body: <p>I use this CSS for create opacity in background of div:</p>
  
  <pre><code>filter:alpha(opacity=50);
  -moz-opacity:0.5;
  -khtml-opacity: 0.5;
  opacity: 0.5;
  </code></pre>
  
  <p>The problem in my case is that this way changes the color of font inside of div and the border color of div. Are there any alternatives that don't change the font's color?</p>
