Grid layout four card feature section with Tailwind

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

I can use grid layout to achieve the desired layout

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

I don't know how to achieve a responsive layout correctly; I can only rely on my feelings. On mobile and desktop, it looks roughly like the design, but the transition process is uncertain.

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

Any suggestions and opinions on this challenge are welcome, thank you very much
