The animations team is an engineering team that aims to enable web developers to deliver a smoother more responsive web.
The team is responsible for maintaining and improving the animations infrastructure, correctly effecting threaded scrolling and related effects (fixed/sticky position, scroll snapping, etc) in the composited property trees, and ensuring that sufficient targeting and hit testing information is generated from Blink.
See also our concrete quarterly objectives.
- Performance - Smooth user interaction and animations (reliable 60fps on today's hardware, 120 fps on tomorrow's)
- Predictability - Interoperable animations APIs on the 4 major browser engines.
- Capabilities - Enable rich scroll and input linked effects popular on mobile applications.
The animations team is driving several ongoing efforts.
