That's alright, it's hideously difficult to read on my 27" retina display iMac so it's a bad experience all 'round.

Funny how that works. I could feel my eyes relaxing when I clicked the link, and I thought to myself that this is what a readable, content-first, website should look like. Using FF on a regular 24" full-HD screen.

For me, it's too low contrast. Extremely thin, monospaced, light-grey font on a black background just doesn't read nearly as well as well-proportioned proportional dark font on a light background — or, if it must be a dark background, yellow text on dark blue is the most legible. Regular Courier over Courier New could help, too, but ultimately a proportional font directs the eyes more easily.

It's the monospaced font, with grey letters on black background that makes it hard to read.

I'm using FF62 on Android and I thought "what a refreshingly simple design", maybe the problem was js that my browser blocked.

thanks for the feedback ... the CSS must be much better now
