React Quote Machine - Project Feedback

Here is my take on the Quote Machine project.
I used some CSS @keyframes for the color change animations and the project was started using create-react-app so it uses React.
I just put the quotes and the color CSS classes in one big quotes array in the state as an array of objects. Felt sorta lazy on the React side but it gets the job done. :smiley:
Any feedback? Here is the link:

Thanks for your comment. Is there a reason to not put quotes in the state? You are right they could have gone in the global scope of App.js instead.

When I say “lazy on the React side” I guess I am just wondering how others approached this project if they used React. My approach made sense to me, so maybe I shouldn’t double-guess my choices. I don’t want to over-engineer something when it’s not needed.
