Feedback page based on CSS Grid

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

I am proud of the fact that I made this project with the help of CSS Grid.

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

There were problems with placing Grid elements. Also with adaptive.

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

I would like to understand why in the mobile version, the bottom block does not take the full width, although I used (grid-row: span 2) for it.
