Social proof section solution. Built using Flex Box and Media query.

Great work on this one.

A suggestions would be

• Your layout is good, but as soon as I resizes it, your elements, at the bottom one, the three boxes, they don't scale down right and just static creating a scrollbar at the bottom of the page and we don't want that. The reason for that is you set a fixed width property on the section and when you browser resizes, your container does not, maybe changing it to width: 100% will be much better since it will dynamically scales itself relative to the viewport.

Overall, the mobile is good and good job^
