Responsive Contact Form Page

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

I might need to revise my CSS and Javascript codes, they look untidy a bit.

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

I had a hard time on JS side, took me a while to figure out why my div did not show up when submit button is clicked and all that...

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

ANY help or feedback is appreciated, thanks in advance :)
