Responsive four cards using Tailwind

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

I worked for the first time with CSS grid using Tailwind and I don't find it very difficult once you get used with it.

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

It was a bit difficult to figure out how to make the second column with 2 cards. I created 4 rows and using "row-span" and "row-start" properties it worked.

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

When is indicated to use grid instead of flexbox?
