Super Fast Transitions
summary
Covers practical techniques for making UI transitions fast: animate only transform and opacity so animations stay on the compositor, use will-change sparingly because it creates GPU layers, batch DOM reads/writes to avoid layout thrashing, and offload heavy work into chunks or web workers. Explains timing with requestAnimationFrame and requestIdleCallback against RAIL targets (100ms response, ~16ms per animation frame, ~50ms idle budget, <1s load) and demonstrates the FLIP technique (grid to fixed) using transforms and crossfades.
