Responsive BMI index calculator - Html Css Js

In this challenge I found myself a bit difficult to manage the Javascript side of the code, especially in managing the form data well in order to get to display the correct result, both of the BMI index and of the recommended weight range.

I had to figure out how to best style the two input types, both the radio button and the numeric input, but overall and with no small amount of difficulty I got as close as possible with the provided design.

Do you have any advice/suggestions/constructive criticism to make regarding the design or even better, the code? I'm here and we can talk about it, I'd be very happy.

cheers
