I created a website (www.techieafrohead.com) and facing an issue on testimonial cards horizontal scrolling. It is smoothly working in desktop browsers but when seen on samsung browsers(Chrome) or in any phone’s (android) browser , scrolling is not smooth or just not scrolling.
i tried making .card-wrapper class overflow-y to auto from hidden, but it creates a scrollbar on the right which makes it look odd because i’m expecting to do that through scroll button. Also, in javascript added a line to control the max scroll amount let scrollAmount = window.innerWidth < 768 ? 50 : 100; // Also finally tried btnScrollUp.addEventListener(‘click’, () => scrollVertically(1));
btnScrollUp.addEventListener(‘touchstart’, () => scrollVertically(1));
btnScrollDown.addEventListener(‘click’, () => scrollVertically(-1));
btnScrollDown.addEventListener(‘touchstart’, () => scrollVertically(-1));….,but all my attempts failed.Let me know how can i fix this issue.
