CSS tried to come for my Job - Cyd Stumpel - CSS Day 2025

CSS has gotten more powerful in terms of layout for the last couple of years, but lately, it’s also been creeping into places that have traditionally relied heavily on Javascript. Features like scroll-driven animations and view transitions are changing what’s possible natively in the browser. As a creative developer, I’ve spent years building animated sites using GSAP, Swup, and Javascript-heavy custom setups. In this talk, I’ll share what I learned switching from full-control Javascript animations to CSS-driven transitions. I’ll talk about what works, what doesn’t (yet), and how these tools are reshaping the creative developer’s workflow. If you’ve ever spent days tweaking timelines or writing math for transitions, this might just convince you to let CSS take over (at least a little).
