Testimonials Grid Section (mobile first using grid and flex)

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

I have implemented the desktop version using Grid and the mobile version using FlexBox. Using two types of layout methods boosts my confidence.

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

In desktop version, an item wasn't stretching all the way through the whole cell. Later I found a property called align-items: stretch which solves the problem.

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

Box shadow is still challenging for me to apply. I can see the two white cards has some shadow, it's hard for me to apply. Anybody help me how to have that kind of shadow?
