QR Code for frontend mentor using sass and HTML

What are you most proud of, and what would you do differently next time?

This is my first post to frontend mentor. I have never done anything like this before. It was also my first time using SASS. I have used css before but I wanted to try something new.

Not sure what I would do differently just yet.

What challenges did you encounter, and how did you overcome them?

Getting setup with SASS. As I have never used it before I was a bit anxious of using something new and getting to grips with it. I pretty much bumbled my way around and watched a few videos on how to get started.

What specific areas of your project would you like help with?

Any insights on code quality and best practices. I never really get a chance to work with other developers, so everything I know / don't know is from my own experiences.
