Show HN: CSS-Only 3D/2D 1D Chess (opens in new tab)

After seeing the 1D-Chess project on the Hacker News front page somewhat recently, the idea came to me to try and make a CSS-only version of 1D chess because it seemed like it might be a good candidate for it.

There is absolutely no JS used for the interactivity or game state for this variant; it's all pure HTML + CSS, and I've added a few fun things along the way just to exercise those constraints a bit more, too.

I've also got a "making of" post for the project linked to from the about box on it if you'd like to learn a little more about how I put it together.
