How to implement slick-slider preview?

Question

JavaScript

Hello! As conceived by the designer, the preview of the slide displayed on the screen should be highlighted with the help of "after-before" (a small triangle at the bottom of the preview). Scrolling preview should not be. Can you tell me how to attach this same "after-before" to the preview at the moment the desired slide is turned on and cancel the scrolling of the preview (this is true in the "autoplay: true" mode)? Thank you!

Answer 1

do it through slider syncing and add your styles to the active slide (it has the slick-current class), the same :before,:after, or customize .slick-dots, but this is a perversion
