mortgage repayment calculator fully responsive solution

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

I'm proud of being able to do the javascript checks. I've also improved some of the semantic and layout of the elements which made it very easy to style.

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

Finding the formula to properly do the mortgage calculations was a challenge LOL

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

Any feedback is greatly appreciated as long as I can learn from it
