Mortgage Calculator in React Vite with minimal 3rd party libs

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

Managed to build with almost no 3rd party libraries. Using only the modular CSS and proper import order, to have CSS rules that can me extended and overwriten without having to resort to !important or increasing CSS specificity.

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

I wanted to implement the form styling, including error states without using form libraries. Dealing with touch state and styling of error messages I did surrender and just used react-hook-form, which is at least a lot more light weight than Formik.

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

suggestions for organizing CSS. could I have made the breakpoint specific CSS more readable.

if had used scss I could have used mixins. but I wanted to try without scss and just use as close to plain vite as possible.
