Social proof section in desktop-first approach using flex and grid

What are you most proud of, and what would you do differently next time?

I'm able to adjust the position of each rating/review card, and how to use two backgrounds in an HTML page.

What challenges did you encounter, and how did you overcome them?

I struggled with how to remove the margins/spaces of each rating in mobile view, as I use desktop-first approach. I realized that I forgot to override the margins of each card to zeroes

What specific areas of your project would you like help with?

I would like to know another way to adjust the margins of each rating/review card without using :first-card or :nth-card([specified_number]).
