Design a Sketch that uses Dom Elements

The sketch I created uses buttons to change the colors of the background. I had to use css code to create these buttons and customize them.

A challenge of mine was figuring out how to change the button background and text color if I hovered over it, but more searching of p5 reference helped me get the code I needed.
