style.css

/*
This CSS is heavily inspired on Fomantic UI, because I really like how it looks,
but I wanted something minimal for my personal site, and not using a whole
framework for a static page.

The dark theme is based on the glourious Ultimate Dark Neo theme for VS Code:
https://github.com/rubjo/ultimate-dark-neo-vs-code/
