3-column preview card component using HTML and Sass

Hello! This challenge is more on the easy side for me, but I wanted to practice more on using Sass and I wanted to test how fast I could finish a project like this one so I picked an easy no-JS one.

I forwent the use of a level 1 heading for this project, as I imagine this component will be part of a bigger project which will rightly contain the main heading.

Feedback on any part of my code is welcome!
