Planets Facts Page in Vanilla JS

Wow! this project was very complex, since i did it only with Vanilla JS. I know that if I did it with React Js I would have done it much faster, but I wanted to do the challenge of doing it only with Vanilla Js. I also started doing it with SCSS but when I had to change the colors by planet there is no way to edit the SCSS from Js, so I had to remove it and work with the variables directly in CSS.

If you know of a way to edit variables in SCSS from JavaScript I'm all ears! Thank you!
