Lightning Talks Day #2 – Konstantin Lebedev
summary
Practical rules for making web animations actually fast: use pointer-events: none on noninteractive animated elements and apply will-change only to known elements immediately before and remove it after animation because promotion to a separate layout layer is expensive; prefer animating only opacity and transform so the browser limits work to the GPU composite stage; use scale / counter-scale for size changes or the FLIP technique for combined size+position; React examples mention react spring and frame emotion.
