Testimonial page with HTML and CSS

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

I am proud of the fact that I did this in just two days and when i was just a beginner about 4 months ago. And next time, what i'd do differently would be to use a grid-columns and grid-rows to implement the bento grid for this css grid rather than using an insane amount of flexbox and grid technicalities (you have no idea how many times i had to review this code for responsiveness).
