title: Changing .css background-color via jquery doesn't work
body: <p>I have an issue when I want to change a background color of my div element via jquery after receiving an ajax respond, it doesn't work.(Code is validated, I tested it by entering a test line in error statement before changing css property and it worked.)
  Here is the code:</p>
  
  <pre><code>#statusbox {
  background-color: #FFFFFF;
  width: 15px;
  height: 15px;
  display:inline-block;
  float: left;
  position:relative;
  left:190px;
  top:3px;
  border-style: solid;
  border-width: 2px;
  
  border-color: black;
  </code></pre>
  
  <p>}</p>
  
  <p>And the jquery</p>
  
  <pre><code>success: function(msg) {
      if (msg['connected']) {
          $('#statusbox').css("background-color", "#00FF00");
      } else $('#statusbox').css("background-color", "#FF0000");
  },
  error: function(error_msg) {
      $('#statusbox').css("background-color", "#00FF00");
  }
  </code></pre>
