How to style an external form within webflow (with css maybe)?


I have signup button where people can sign up for our newsletter (big orange button). I got this Javascript code from them with some basis questions, so the answers get immediately implemented into our datebase within their program. (the JS code is on the homepage settings)

My problem now with it is that it looks terrible:

My question is how can you style this form within webflow?
Like adding some padding between the questions for example.

Love to hear!
