How to make Shopify Buy Now button as slider on mobile format

[pawprintstudio]

I would like to make the buy now images at the bottom into a slider instead of scrolling:

The same way it's displayed on Shopify:

Hi @pawprintstudio 

The buy now button in Shopify store can't not be edited by the Custom CSS

Best,
