How to make a block in the center of the slide so that it stands out?

Question

css

Good afternoon!
There is a slide https://codepen.io/acornTeam/pen/RQKXLE (tiny slider)
3 blocks in the field of view, by clicking on the arrows they move one by one to the side (either to the right or to the left).
Question for connoisseurs: How to make the block stand out in the center, for example, with a different background or shadow?
Are there other plugins that can do this?
