title: Positioning div to top of viewport using jQuery
body: <p>How do I position the #lightbox div to always be at the top of the viewport?</p>
  
  <pre><code>$(document).ready(function(){
      $('.mehr').click(function() {
      $("body").css("overflow", "hidden");
      $('#lightbox').css({'visibility' : 'visible'}).animate({'background-color': 'rgba(0, 0, 0, 0.9)', 'opacity': '1'}, 500);
  });
  </code></pre>
  
  <p>Many thanks for any help!</p>
