I’d like to do an animation that consumes about 2/3 of the page that happens once and then disappears and the main elements of the page will then appear in the area previously used by the animation. I’m entering a room, the animation shows the portal first far off, getting larger, then going white and disappearing, leaving the page content. I can do the animation but so far, all the animations I’ve done repeat continuously. Is there a setting for just once through that I’ve missed?
