Question

JavaScript

Good afternoon!
Tell me how you can add a few more slides to this script codepen.io/mrspok407/pen/NRxBWa

Answer 1

You also have elements:
pages__item--1, 2
app__text--1, 2
app__bgimg-image--1, 2
Just copy and duplicate them, but with numbers 3, 4, ... and put the necessary styles. As far as I can see, you don't need to touch the script at all

Answer 2

it completely breaks down in this case ...
