responsive registration with client side validation

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

I like the design where the card snaps between breakpoints rather than being fluid, IMO it gives create control of how the text is layed out.

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

Client side validation, it's my first time doing it so I'm still learning and want to practice more.

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

Best practices for client side validation, JS in general. I declared 6 const, I feel like it might be two much or my code is to verbose in places.
