Contact form fully responsive solution

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

I'm proud of the javascript form validation, it's something I had never done before.

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

I had issues styling both the radio buttons and the checkbox, but I ended up overcoming the obstacle.

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

I'd like feedback on the form validation but I'll appreciate any advice I can get!
