Facebook is slowly adding features that allow you to do more JavaScript in their world. This started with FBJS (after mock ajax), and today they have announced FBJS/Animation, an open source animation library that not only works inside Facebook, but also can be used stand alone.

There is a nice PLAIN TEXT HTML:
  <!-- Simple --> <a href="#" onclick="Animation(this).to('background', '#fff').from('#ffff4b').go(); return false;">Flash</a>   <!-- Hiding / shrinking --> <a href="#" onclick="Animation(document.getElementById('container')).to('height', '0px').to('opacity', 0).hide().go(); return false;">Hide this div</a>.   <!-- Revealing --> <a href="#" onclick="Animation(document.getElementById('about')).to('height', 'auto').from('0px').to('width', 'auto').from('0px').to('opacity', 1).from(0).blind().show().go(); return false;">About Facebook</a>.   <!-- Easing --> <a href="#" onclick="Animation(document.getElementById('container')).to('height', '0px').to('width', '0px').to('opacity', 0).blind().hide().ease(Animation.ease.end).go(); return false;">Hide this div</a>.  

It is great to see open source libraries like this come out of Facebook. I am curious why they decided not to use one of the other animation libraries out there. If you know, comment below!
