Four card feature section

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

I find that the result is very close to the model. What I would change: I forced myself to use grids, but I wonder if I should have tried with flex boxes for this one.

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

The organization of the in desktop version with the 4 sections that are at different heights. I went back several times to websites that explain how to use grids because it wasn't obvious. Not sure if my h1 is an h1. I didn't find an alternative.

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

The grids. I would like to practice on other challenges. Which ones do you suggest?
