Mobile-First Intro component with sign-up form (HTML, CSS, JS)

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

Proud to finish yet another challenge. I lost some time due to the lack of efficiency of my form control functions from an algorithmic point of view. I finalized a first functional version that I didn't like at all, with control only at submit level. After a night's sleep to get some perspective, I came back stronger with a rework of these functions to make them simpler and more readable. I added a control for each change to the form. I managed to make the system more complete, easier to read and save lines of code.

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

The frustration of knowing full well that I was going in the wrong direction. I went to the end of the road because it was necessary. I rested. Then I went back and reworked the code's organization, efficiency and readability. So taking a step back was the best solution.

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

I don't know. But as always I'm open to any constructive comments that will help me improve.
