title: jQuery filter function not working
body: <p>I'm trying to change the background color of all the divs which have a distance of 100px or more relative to their parent's top.</p>
  
  <p>I'm using:</p>
  
  <pre><code>$('.box').filter(function () {
      return $(this).position.top &gt; 99;
  }).css('background', 'red');
  </code></pre>
  
  <p>Which doesn't seem to work.</p>
