What happened to the CSS?

Yes, I practically removed all the CSS file from this website!

This gives me some advantages:

If you have problems because of the absence of a dark theme, don’t complain: install Redshift.

Update 2022-07-21: now I’m using GitHub’s primer Jekyll theme CSS because it’s more responsive and more elegant.

Update 2022-10-08: a dark theme has been implemented with < 10 CSS lines. You need to set your device system settings in dark mode, or you can toggle dark mode using the browser’s development console.

/* set the background color to black when client requests dark mode and invert the colors
