Build a multi-stage timetable for a conference — fully in modern CSS.
Each hour grows automatically to fit all sessions.

🍾 heavy use of subgrid.
🍾 round() and mod() to place sessions accurately
🍾 scroll-driven animations for sticky stage headings

Has anyone else seen this in iOS 26? Sticky and fixed elements shift slightly out of view when scrolling down, then snap back when scrolling up. I made a demo to test it: cdpn.io/pen/debug/Qw... Curious if others can reproduce.

I built a little tool to check color contrast across an entire palette. 🎨
