Tip Calculator built using Reactjs & TailwindCSS (+ dark theme)

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

Challenge was built as practice for TailwindCSS, starting to get the hang of Tailwind and looking forward to start building more advanced projects with it.

This challenge also contains a dark theme that is applied automatically to those who have their system preferences set to dark mode.

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

Any general criticism would be appreciated, but mostly I would like criticism with TailwindCSS and my use of it.
