Social Proof Section using FlexBox

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

I'm proud of the fact that now I am able to understand what concepts do I need to use to get the job done.

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

I think the biggest challenge was to align the reviews in a staircase layout just like how they are aligned in the preview.

Here's my approach:

1. I set the width of the container to a slightly larger with compared to the items inside.
2. After that I did align-self on all the items inside the container giving them values start, center and end

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

I would like some advice on my approach that I used to align the items. Is there a better way to do it?
