title: How to remove css property in jQuery
body: <pre><code>if(prev_clicked)
  {   
      $("#accordion li a.category").css('background-image', 'url("img/off_all_channel.png")');                    
      $("#accordion li a.comment").css('background-image', 'url("img/on_all_online.png")');                   
      $(".icha0").removeProperty("background-color");
      $(".icha0").removeProperty("opacity");
  }
  else
  {   
     $(".icha0").css("background-color","#D5D5D2");
     $(".icha0").css("opacity","0.70");
  }
  </code></pre>
  
  <p>I am trying to remove two css properties that I added but It seems not working.
  Any though?</p>
