Social proof section with grid/flex layout SCSS and dark theme

Hi there!

In this challenge i tried to use SCSS to understand how it work, the page seems to work at the end, but i'm not sure if i used SCSS correctly, i mean, other than dividing the css in multiple folders (abstract, base and layout in my case), nesting some classes in scss way and use mixin instead of media is the same as a normal css file, maybe i'm skipping something or maybe scss helps more on complex pages?

A feedback on this topic will be really appreciated! Cheers!
