CSS Clicker Training: Making games in a "styling" language (39c3)

CSS is a programming language, and you can make games in it. Let's install NoScript and make some together! This talk is about how HTML and CSS can be used to make interactive art and games, without using any JS or server-side code. I'll explain some of the classic Cohost CSS Crimes, how I made [CSS Clicker](https://lyra.horse/css-clicker/), and what's next for the CSS scene. I hope this talk will teach and/or inspire you to make cool stuff of your own! --- *Content notes:* - Slides feature animations and visual effects - Short video clip (with music) will be played - Clicker sound at the end of the talk --- Slides will be available after the talk at: [https://lyra.horse/slides/#2025-congress](https://lyra.horse/slides/#2025-congress) Licensed to the public under http://creativecommons.org/licenses/by/4.0 about this event: https://events.ccc.de/congress/2025/hub/event/detail/css-clicker-training-making-games-in-a-styling-language
