Overlay Transition & delay before popup.

I would like the overlay to slide in from the top and have a few seconds delay before the popup fades in. I am currently using ninja popups but your modal solution is so much easier and less resource intensive. I have clients that want to promote cetain films so I am using the background overlay as the film poster and then the opoup as a ‘buy tickets button’.
