update:- This is just an example that i am using in webpage. Web page
has different number of sections apporx. 20 sections and all are
having 10 or more images. So when we are running that much images with
animations the performance goes down.
I have checked it on mac Safari 11 & 12, the animation and scroll is
not smooth. There is jerkiness while scrolling and animations are very
slow with jerks.
