Testimonials using CSS Grid

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

I was able to implement CSS Grid here with less difficulty.

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

Writing pseudo-elements, I don't know how to do these, so I had to use to chatgpt to understand it (although I am not proud of it)

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

Learning about pseudo-elements and if there is any other feedback, deeply appreciate it. Please preview the site because, sometimes the screenshot generates the wrong result, so would appreciate if anyone can tell whats wrong
