Responsive landing page with one media query

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

it took like 30 mins to realize i could only change a type="" to make everything work well. Next time i will def take in account any class, type, id, etc. That could make my code work.

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

the main challenge here was making the button focus on the first not filled input. I technically did the code for that but i didn't knew that when you disable an element with JS, you cant neither interact with it from JavaScript(that means you cant click the button), so instead i just changed the type of button so it just don't do anything but i can still click on it.

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

I am not sure here, since any help that i need on JS topics that i haven't seen before I just look it online and learn so I can think on a solution.
