testimonials grid responsive with css grid

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

getting the hang of css grid, i'm still struggling a little bit with the variables because there are always a few exceptions, and still doubting how to implement those.

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

the mobile grid, it looks bad of you make the browser small, but looks good if you put the browser in mobile responsive mode.

plus i somehow began in desktop design instead of starting from mobile.

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

the mobile grid, it looks bad of you make the browser small, but looks good if you put the browser in mobile responsive mode. from whast i see the code is good, so i don't know what the right solution is.
