I'm trying to mimic these CSS modal windows - http://tympanus.net/Development/ModalWindowEffects/.
I've centered the modal in the stylesheet, on click, it appears, and I'm using 'from' to animate towards the
center. However, I close, then re-open and it doesn't re-animate.
Wanted behaviour - click button, slide in window. Click again, hide the window. Simple modal window, but
can't seem to get the window to re-animate.
