I am going to share my current code on code sandbox: https://codesandbox.io/s/gifted-mcnulty-6ejcx
I have attempted at creating a boolean and then using a button to change the state of that boolean which should in turn change the theme of the website. I would love some help in getting this to work and if you have any ideas on whether I should have multiple buttons for the themes I want to display or just 1 button which can cycle through more than 2 themes.
Any advice is much appreciated :)
