Calculator w/ localStorage to remember user picked theme

Tread ⚠️carefully⚠️ in my CSS index code... You will puke at the mess 🤮

In this challenge, besides copying the CSS and html layout and some JavaScript mess to make a functional calculator, I have also made it with localStorage 😎 impressive? no... its not... But will it help our users? Yes, yes it will!

I am kind enough to considers the eyes of man such as hermits who like to use their cellphones in the dark, we don't want them to get blasted with white light.

Areas I am unsure of...

There is only one thing I am unsure of, the mess I have created in my index.css file. I have given up on arranging my key:value pairs in easy to read form. I prioritized how the frontend looks than how clean my CSS and script is.
