  Ok, let me be honest here…
  DISCLAIMER:
  I drew inspiration and a little CSS from the now defunct
  http://whatthekeycode.com/
  
  Still, it's different in a lot of ways.

  This is the perfect single page app by the way :-)
  
  It really won't tax your network connection once it's loaded,
  this file is all there is!

  It is fully commented and – even better – narrated.
  It uses all of HTML, CSS and Javascript comments.
  So if you ever forget the syntax - here's your refresher!
