Flexbox, multiple selectors css

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

Having completed the project efficiently, the final result is similar to that proposed in the challenge. Next time, I would start working on mobile and then develop the desktop model.

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

A challenge at first was aligning the texts vertically, but with a little research I was able to get around this situation.

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

I would like help to know if the css is well organized and if it is possible to reduce the number of lines used.
