I was wondering how it did the screen update with CSS and it turns out it uses a little Javascript to update the text content: https://github.com/ManzDev/twitch-casio/blob/main/src/index....

This is beautiful. I zoomed in stared at the switching digits like I did as a kid in the 80s with my own Casio watch. Thanks for posting this.
