How to make an animation when scrolling the page to a certain place?

Question

Animation

At the same time, so that when scrolling back, the moved elements remain in place, and not "fly back"?
For example:

Answer 1

You need to read about parallax. The theme is that the elements are located absolutely, but change their position depending on the value of the call. There are a lot of libraries for implementing parallax, but if you sit and think, you can implement it yourself.
