Social proof section using SMACSS

Hi, what's up? I've remade this project (I had already done it a few weeks ago, but now more organized) using the SMACSS methodology for structuring projects once again, and as always it helped for having stylesheets more modularized. Likewise, I used my own mini-library of SASS mixins to give me a hand with the media queries, flexbox, and grid :D.

I'd like to mention that I added a smooth animation when hovering the testimonials comments.

As always feedback is appreciated :D.
