Hey Sulami, this is off topic, but how did you get those nice sidebar footnotes? What theme are you using? Or how did you edit the css?
This is the tufte-css, with some modifications.
Raw css is here: https://github.com/edwardtufte/tufte-css
My additions on top (and all other source) here: https://github.com/sulami/sulami.github.io/tree/develop/css
