Mobile first solution (HTML+CSS+Javascrip vanilla)

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

I managed to stylize the radio inputs and deliver a result that met the brief. I don't think I'd do it any differently, even if using a framework or a library would undoubtedly be quicker - my aim is to work from the basics.

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

It's been a while since I've used vanilla javascrip. I've tried to do a few clean things by cutting and re-cutting my functions to limit the responsibility of each, although there's still a lot of room for improvement.

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

I don't know, but as always... feel free to suggest areas for improvement.
