Some comments on this from my side:

- You people totally overwhelmed my website... I use(d) Firebase static hosting because it's completely free and super simple, which reached the 10 GB monthly limit now. I changed to Cloudflare in the meantime, but it'll need some time for the DNS records to update. IN THE MEANTIME, PLEASE USE THE GITHUB PAGES LINK INSTEAD: https://benjaminaster.github.io/CSS-Minecraft/

- I made this almost three years ago now, to try out the limits of what's possible with pure CSS, and to test out the then-new CSS :has() selector.

- This project never got much traction until now, so I never bothered to write about how it works. Simon Willison now already wrote a blog post about it, so I guess I don't have to anymore... https://simonwillison.net/2025/May/26/css-minecraft/

- For the best experience, please view this on a desktop browser, either Chromium-based or Firefox.

- The source code is at https://github.com/BenjaminAster/CSS-Minecraft. The "index.pug" and "main.scss" files contain the actual source code; the rest is mostly just the compiled output.

- Here is a video of me building a house with it: https://www.youtube.com/watch?v=OH8-Y9frP5k
