title: jQuery not method for opacity
body: <p>I am not able to see the opacity in IE8 browser.
  I think its because of the <code>not</code> method in jQuery....
  Can you tell me how to fix it?
  Providing my code below:</p>
  <pre><code>function soccerMatches(matches) {
      var $cricket = $('.color'),
          matchesIds = [],
          $soccers;
  
      $.each(matches, function(i, match) {
          matchesIds.push('#cricket' + match.title);
      });
  
      $soccers = $(matchesIds.join(', '));
  
      $cricket.not($soccers).addClass(&quot;testing1&quot;);
      $soccers.css('opacity', 1);
  
  }
  
  .testing1 {
  
      opacity: 0.33;
      -ms-filter: &quot;progid:DXImageTransform.Microsoft.Alpha(Opacity=33)&quot;;
  
  }
  </code></pre>
