Mobile adjustments

video of the elements

Hey everyone,

A question regarding my portfolio website.
I have made this fold-out div block with a slider for the large web pages, but this design doesn’t work on mobile. I’m having a lot of trouble changing this.

When I try to delete these folds to only keep the slider on mobile, the fold-out also disappears on the pc version of my webpage. Any idea how to fix this problem; so only keeping a small slider on mobile.
