title: Change a specific property in css using jquery
body: <p>I want the online icon to blink. Put this in my js code:</p>
  
  <pre><code>function blink(){
      $('ul.left_menu li.online').delay(100).fadeTo(100,0.5).delay(100).fadeTo(100,1, blink);
  }
  </code></pre>
  
  <p>What happens is that the whole link is blinking. Is there any way to access a specific property in jquery?</p>
  
  <p>My css:</p>
  
  <pre><code>ul.left_menu li.online a{
      width:166px;
      height:25px;
      display:block;
      background:url(../images/online-status.png) no-repeat left #dad0d0; 
      background-position:5px 5px;
      border-bottom:1px #FFFFFF solid;
  }
  </code></pre>
