Testimonials grid section with grid and flex

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

I'm glad I got my solution to even look close to the design. I'm most confident with how I placed the grid items. I don't know if making named grid areas is the best way to go, or by telling the grid items how many rows/columns to span,

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

Placing the grid. I tried using "place-content: center;" but I couldn't get that to work (I know there has to be a reason.) so I used the horizontal auto margin method instead.

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

I feel like I need to get better control of grid placement, any feedback for use in the future is appreciated.

Should these footers with copyright info ~always~ be placed at the bottom?
