7,075 PointsJS Doesn't want to run the animate.css class

Just shoots to the left instead of performing the animation when the onclick function executes.

230,688 PointsI see a few issues:
- there is more than one element with the same ID "surprise" (ID's must be unique)
- there is more than one nested element with the same "onclick" function
- the "zoomOut" function wipes out all the original classes, which causes the centering to be lost (jump left)
- with no "animation-duration", the animation will happen instantly
- you may want to add "
animation-fill-mode: forwards;
" to keep the faded-out button from re-appearing
