title: change margin-left with JS
body: <p>I want a dynamical margin-left on a given div.</p>
  
  <p>I tried this code :</p>
  
  <pre><code>window.onload = function()
  {
      var pageWidth = window.innerWidth; 
      var size = (pageWidth - 200 ) / 2;
      $('#search').css('margin-Left', size));
      alert(size);
   };
  </code></pre>
  
  <p>which doesn't work (the alert is here just for test purpose), the problem is coming from the ligne <code>$('#search').css('margin-Left', size));</code> but I can't find out where...</p>
  
  <p>I've tried with a lowercase <code>l</code> on margin-left and didn't work.</p>
