Onboarding Pricing Component - Pure HTML & CSS

My first FM challenge!

Question: Is the way I used the :root variables in media queries to adjust font sizes a good solution? Ended up storing only the intro card font sizes and I'm not sure if I should've done that lol!

I know this challenge is on the simpler side, but I really want to establish my pure HTML & CSS before I move on to more complicated challenges!

P.S Congrats to Matt & the FM team for creating such an amazing platform!
