Responsive Form with Validation and Animation

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

I mostly learned how to style forms further, along with validation via JavaScript. I had done a smaller version of this before, but this was a bit more complicated as this had several elements to manage.

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

I find that I struggle to remember how to style form elements often. With how common this seems to be I feel as though I should take some notes to refer to, as I find myself going back and having to research how to style certain elements repeatedly.
