What is the name of the slider effect?

Question

css

I stumbled upon such a slider https://revolution.themepunch.com/parallax-zoom-sl... It
is smoothly approaching, this is understandable.
At first I thought that these were separate pictures divided into layers, to which volume was added through css.
As it turned out, the picture is whole, but how exactly does it divide it into parts, turning it into layers? Or maybe it looks like it.
I’m more interested in what this action is called in order to search for information in more detail
Ps I didn’t encounter this before, it just became interesting how this can be implemented in practice

Answer 1

As it is written in the url, it is called - parallax zoom slices (parallax with zoom and slices)
