Audiophile e-commerce website | React | Typescript | Tailwind

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

At the beginning, it was challenging for me to manually validate the form and make it work consistently across Chromium and Firefox. For some reason, e.preventDefault() didn't behave as expected in Firefox, so I had to implement the form validation through a button function instead. Additionally, I created my own component to handle the input styles for the checkout validation. Next time, I'll definitely use React Hook Form to streamline the process.

Any suggestions for improvement are welcome!
