Dark Mode

Dark mode have been added for those that feel like light mode is too bright for them. I myself prefer dark mode when I use my phone, but I chose to have both of them because some physically cannot read light text on dark backgrounds ¹. It was not that hard either, as some may think that it involves JavaScript and user interaction, it is a standard for around 5 years ².

So, using some proper guide I did just that and basically copied from Dark Reader plugin ³.
