How to make slide full width?

Question

Layout

Hello.
The essence of the problem is this: after loading the page at resolutions of 991px or less, several https://codepen.io/rusl10/pen/jJJVyr "> appear in the frame instead of one
slide . I understand that it's most likely in styles, but I used to write the same styles and everything worked fine. I would be glad for any hint, thanks
