Responsive learn to code sign up form

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

The responsiveness of the site. It's previously taken me a long time to figure out how to set up the responsiveness of past challenges. Starting with a mobile workflow really helped speed up the process.

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

Form validation was cumbersome and, although I did not implement the best form validation, I learned some easy ways to validate minimal forms like this.

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

Any feedback would be welcome!
