Hi Guys, I hope you could point me on the right track to be able to make a animation in and reverse approach on this current pen that I attached. My goal is when I enter the section which will be active I wanted to animate all the elements inside (that I can do).  My problem is reversing the animation before leaving the current section. Anyway, as you can see on the pen its a scroll wheel transition. Best Regards, Mikhail   See the Pen zjvGmZ by miksv (@miksv
