four-card-feature-section HTML&CSS responsive grid solution

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

I think this one went well. If I started again, probably I'd come up with a different solution, but I'm happy with it as it is.

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

When it came to desktop design I choose to solve it with the grid. I made a mistake writing repeat function, inversed arguments so I had a bit odd outcome at first, however after googling function's definition I realized my mistake and fixed it.

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

I think I did well this one, however feel free to leave any suggestion u may have, I'll appreciate it.
