Four card feature section flex, grid, sass

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

1, I finished this project after 3 days.... I didn't give up. 2, I have a deeper understanding of the rank of the classes

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

In the end , I made the 1440 view using a grid, but the grid-gap is fixed, but when the screen goes larger, the vertical gaps between the divs are no longer the same.

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

For the minimal size, how to define it's minimal enough and the cards shouldn't shrink anymore?
