Fix janky UI animations by enforcing transform and opacity-based motion instead of expensive layout changes. A deterministic review workflow analyzes your animation code, surfaces performance violations, and suggests concrete fixes to ensure smoother, jank-free interactions.

Scroll-linked motion causes layout thrashing when animating properties other than transform and opacity. Enforcing transform and opacity-based motion by default avoids expensive layout changes, ensuring smooth scroll-linked motion across CSS, WAAPI, and related tooling.

The best way to review UI animation code is using a deterministic workflow that applies predefined best practices. This process analyzes your CSS and WAAPI animations, identifies violations of transform and opacity constraints, and provides concrete, code-level fixes.

Yes, the animation review process works with CSS, WAAPI, and related tooling. It applies a predefined set of constraints to your current UI animation work, ensuring transform and opacity-based motion is enforced across these web animation technologies.

Avoid animating properties other than transform and opacity whenever you are adding or changing UI animations or refactoring janky interactions. Animating other properties triggers expensive layout changes and repaints, degrading web performance and causing visible jank.
