Animated, responsive solution using React Hooks and Sass

Thank you! Just forked your solutution and will try to learn something.

I only came up with idea of gradient and coded it like this: background-image: radial-gradient( 700px 700px ellipse, rgba(255, 255, 255, 0.2) 0%, rgba(255, 255, 255, 0.2) 20%, rgba(255, 255, 255, 0.1) 20%, rgba(255, 255, 255, 0.1) 30%, rgba(255, 255, 255, 0.05) 30%, rgba(255, 255, 255, 0.05) 40%, rgba(0, 0, 0, 0) 40%, rgba(0, 0, 0, 0) 100% );

It was not the best solution though ;-) Yours is working just perfectly!

Wow! I'm really impressed both with animations and the gradient behind the winning symbol. I'll study your code thoroughly, cause you solved some issues I was not able to :)
