My process

Built with

• CSS custom properties
• Flexbox
• CSS Grid
• Mobile-first workflow
• Typescript
• React Hook Form

What I learned

This challenge was a great way to dive slowly into Typescript for more complex application. I've build a form with React Hook Form, with yupResolver and Credit Card Validator for the first time. I've faced many problems with css animations and giving input with border radius property a gradient outline. It was also a great way to review knowledge in Regex by field validation.
