Social Proof Section - Only CSS Mobile-First workflow

first of all I do not know if you planned for the "attribution" section to be on the top right of the project. I like it their and I will try to standardize mine their from now on and see how it works that way it is always in the same place and out of the way.

while the design is responsive I think some fixed widths or max-widths on the elements would help the design make it like better across all screen sizes and more consistent depending on random size screens

Good work on this one. Layout is good and the mobile state as well. @palgramming already mentioned a key point which is important. Referring to the usage of height: 20vh in the review selector.

Also when going in mobile state, there is an appearance of scrollbar at the bottom. You could get rid of this by just removing the width: 100vw in your body tag.

Overall, you did a good job in here and the layout is really good^^
