title: set font size in jquery
body: <p>I'm not able to change font size using Jquery. I want to change font size of a div. I have defined default font size for body as 12. I tried to change it as follows, but it didn't work :(</p>
  
  <pre><code>$("#SelFontSize").change(function(){
  $("#"+styleTarget).css({'font-size':'"+$(this).val()+"px'});    
  });
  </code></pre>
