title: get value of offset() and divide it by factor of windowheight
body: <p>ive the following problem:
  on window resize im fireing some events and one of them is this:</p>
  
  <pre><code>var height = $(window).height()
  var getfactor = $('.second').offset().left/height
  var getleft = getfactor*height
  </code></pre>
  
  <p>with this im doing:</p>
  
  <pre><code>$('.second').css('left', getleft);
  </code></pre>
  
  <p>but on window resize its always on the same position, and no left is been manipulated.</p>
