responsive sign-up form with client side validation

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

I am most proud of the form validation and the wrapping of the two larger components. I would probably attempt a more effective way for form validation but I am still proud of the current version.

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

validating the email was a challenge but it introduced me to regular expressions which I used to solve that problem.

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

I would appreciate advice in validating the email in particular. I used a reg expression but I still don't really understand it.
