Css only, with level4 :has() selector [NOT WORKING ON FF]

Hello everyone !

For this challenge I tried something new, my goal was not great responsiveness or clean & semantic code.

I wanted to experiment one of the latest CSS selector (:has()) and see what he has to offer. And I very exited ! Modern CSS will soon be really fun !

With it, I was able to remove all the JS needed to create such apps ! (I put some code snippet in the readme)

NOTE: The website will work on every browser EXCEPT Firefox (you can add experimental flags in order to make it work in FF, they should support this selector soon Implement the :has() pseudo class / BugZilla
