I haven't used SASS or SCSS in anything besides codepen before so apologies if this is a basic question, but my CSS was working fine, but I wanted to nest some tags, and when I setup the SCSS and SASS dependencies and changed my filename to .scss, all of my formatting went away. I read something somewhere about importing an scss file into the css file, but I'm not really sure how to accomplish that. 

Here's a link to the code sandbox: <https://codesandbox.io/s/oj15rk1vw9>
