Validating simple email signup form. JS, CSS, HTML

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

Got to work on JS form data managament, which was fun. Also got to practice some CSS sibling selector stuff, which was useful and worked well.

Also quite happy with the way I handled the success message, without having to jump between pages.

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

Nothing big really, some layout glitches which had to be investigated and fixed.
