Responsive social proof section build with grid & flexbox

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

The css portion was quite simple.

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

Background images were almost invisible , could not tell here they begin and end.

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

I would appreciate any feedback regarding the media queries :

• Is there any duplicate and or unnecessary code ?
• Have i missed something regarding the design ? Thanks for taking the time :)
