Responsive mortgage repayment calculator

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

I feel I leveled up with this one! I had to tackle many unplanned challenges. It works well.

• I solidified my DOM manipulation proficency
• I practiced JS a lot more than I expected (👍🏾)
• I used regex validation for the first time
• It was surprisingly harder than my calculator project

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

• My estimating skills are bad: Originally, I estimated I could do it in just 8 hours. Let's just say it took me way longer.
• As I didn't have a clear vision beforehand, my code started to be spagettified. I still need to refactor it! I know!
• I wasted a lot of time trying to implement a way to prevent the user to type forbidden character when at the end, a simple regex validation is good enough IMHO.

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

• Any advice on the best way to refactor my JS code
• How to organise my CSS file better?
