title: JQuery selector not working with id
body: <p>I am trying to select HTML elements by ID in order to modify their attributes 
  but for some reason it is not working. I have defined my elements as:</p>
  
  
  
  <p>When I try to select the elements by doing the following I do not get any effect. </p>
  
  <pre><code>function handleClick(id){
      var ID =  parseInt(id);
      $("#ID").css({"background-color": "white"});
  }
  </code></pre>
  
  <p>However, if I make the call with the following instead I get the desired effect: $("#16").css({"background-color": "white"});</p>
  
  <p>How can I change my code so that I can do the changes based on the id parameter?</p>
