Sign Up Form with verification

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

This is my first time using RegEx to verify email input field and its such a simple and efficient method

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

I had problems with the resetting of the styling of each field individually when the field isn't empty anymore but i did figure it out somehow and integrated a function to do the job . It was a great challenge
