It's a nice challenge I felt confident all the way while coding it.. it shows how doing the newbie challenges were fruitful. The only issue I had is when testing responsivity with dev tools. for ipad screen and above, it stops scrolling mid-way through the last card. I'd appreciate it if you tell me whether this issue is on your device aswell or not + feedback and tips to improve is always welcomed :D
