A 3D scroll animation that lets you slowly rotate a tablet towards the viewer while scrolling. With the help of 3D perspective you can achieve a great effect in a few simple steps and even use animated videos instead of a static image. I use this setup in one of my case studies in my portfolio.
The Screenshot is scrolling as well. If you don't want that, use the structure of the tablet below and insert an image with the class ipad-screen instead of the BG Video.
