Single price grid component Solution

I used SCSS for the first time here. I don't know much about it, i wanted to get started with it because i found out we can nest things here. Ive a question! I could be wrong but i think most people would initially think abt writing SCSS the same way they write HTML by nesting every single element. but wouldn't it be wrong?? bcs when it gets transpiled then there would be too many selectors and the browser will have to go through all that making it a bit slower? does that make any sense?
