The “linear()” timing function is a game-changer; it allows us to model physics-based motion right in vanilla CSS! That said, there are some limitations and quirks to be aware of. I’ve been experimenting with this API for a while now, and in this post, I’ll share all of the tips and tricks I’ve learned for using it effectively. ✨

The linear() timing function enables physics-based animations like springs and bounces in native CSS without JavaScript libraries. By specifying multiple data points instead of Bézier curves, developers can create smooth, natural motion that runs on the GPU. The article covers implementation techniques, performance testing results showing minimal impact, limitations around time-based constraints and animation interrupts, and best practices for using CSS variables with @supports fallbacks for browser compatibility.
