title: How to do page / content transitions
body: <p>I'm quite new to this all so sorry for my lack of terminology.</p>
  
  <p>I was looking at <a href="http://www.estudiopatagon.com/tf/wp-vcard-colores/" rel="nofollow">this site</a> and I was wondering how I do the content/page change without reloading the page.</p>
  
  <p>Could someone point me in the right direction? What is that JavaScript? CSS transitions? jQuery?  Or could you show me some code? Any help would be amazing; I've been looking around for a while can't find anything like it...</p>
