/* 
* Hi and Welcome to Codepen!
*
* My name is Ignacio and I am looking for a Dribble invitation.
* Please contact me via twitter if you have 1, 
* I would like to have 1 hehe :)
* 
*
* Finally I can reproduce in CSS what I managed to design in Photoshop. 
* Still not all browsers allow for the creatives to reproduce everything.
* We still have browser compatibility problems.
*
* I will keep publishing examples to help push the web foward.
* PLEASE Like, Heart or Share if you like, and don't forget to follow. 
* Thanks.
*
* Now let's animate it :)
