Making a 3 column grid responsive with horizontal scroll

Hi, I’m having trouble turning a 3 column grid with cards be responsive the way I want them to. Instead of stacking up i’d like the cards to be on a 1 row horizontal div with touch scroll (on mobile).
The sections i’d like to do that are: “we didn’t reinvent the well, just PPC”, “membership benefits”" and “pricing”.
I’d like them to look like the reviews section “Clutch/upcity reviews”

Thank you!
