First time using SCSS! I love it! It's so convenient!
One thing I wish I had done differently is not nesting. I don't know why I was nesting at first... maybe because I was using SCSS for the first time?and it felt cool? But when it came to do media queries, it was so inconvenient to deal with specification etc. I'm gonna make sure not to do that again if I don't need to.
One problem I kept having, with this solution, was that every time I would save, and my live server would reload, the font-size of random paragraphs would appear larger than before I saved last time. And it was weird because I didn't even touch the font-size of those paragraphs. So, I would stop the live-server and open it again, and the font-size would be back to normal. Then I'd save again, and the font-size would appear larger. Ugh, it was such a hassle.
But yay I'm happy with the result!
