All solutions

I've done this webpage before with basic html and css this time I used react.js jsx and scss. This is the first web app I've made without a tutorial so I wanted to start out easy and work my way up. I didn't really have too many hang up's with this since I've don't this before.

When entering the card number info if you just smash the numbers in really fast it will break the spacing mech that i have in place. I had the most problem with that part of the javascript. The styling of all the layers was also a big issue for me I think I can find another solution to it ,but will have to start from the beginning and rework the project. I hope in the future when I finish learning react I can redo the project in react

Feedback is welcome. I'm looking forward to your feed back on what I could improve.

Would like to mainly know what your thoughts are on my js. "Feedback welcome".
