title: USATODAY transition effect with url change
body: <p>Sorry for my title, I don't know how to ask this...
  If you go to www.usatoday.com and if you click in any link there is a transition (cool ones) I want to ask if someone know how to change the url example:</p>
  
  <p>You click /news/ and your are on /sports/ it makes a transition as it is a slider but the url changes, as it is another page...</p>
  
  <p>If someone understands what a want to ask, it will be very helpful.</p>
  
  <p>PD Sorry for my bad english</p>
