Responsive Testimonial section with CSS Grid

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

Proud about the fact that I've built two layouts with Grid and with each one I'm learning new things and will be playing around with them/using them more often overtime.

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

I actually thought of using grid-template-area to achieve the layout for large screens, but then when I finished the mobile version and was ready to build for large screens it was like the ideas and tips I had picked up from a CSS Grid youtube video I watched had just puffed out of my head into thin air lol, I tried assigning the grid-areas to each card and the container as well, but the layout wasn't taking the expected form, didn't want to cheat myself so I couldn't go back to rewatching the video and doing the challenge at the same time, so I ended up using grid-column and grid-row to get my results. However, I'd be going back to break everything down, rewatch the video again and try doing it with grid-template-area

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

General review, critiques and tips are always appreciated, thank you!
