SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses and resolves animation stuttering and jank in user interfaces, ensuring smooth visual performance across web and application animations.

Core Features & Use Cases

  • Performance Auditing: Analyzes CSS and JavaScript animations for common performance pitfalls like layout thrashing and inefficient property usage.
  • Targeted Fixes: Provides concrete code-level suggestions to optimize animations, focusing on transform and opacity properties, and efficient DOM measurement.
  • Use Case: When a user reports that a modal transition is slow or a scrolling animation feels choppy, this Skill can be invoked to diagnose the exact cause and suggest specific code changes to fix it.

Quick Start

Use the fixing-motion-performance skill to review the file '/src/components/Button.js' for animation performance issues.

FAQPage Schema
Why does my web animation stutter and how do I fix layout thrashing?

Animation stuttering often stems from layout thrashing, where rapid DOM measurements force synchronous recalculations. Fixing animation performance involves auditing these measurement loops and batching DOM reads and writes separately to eliminate jank.

How do I optimize scroll-linked animations to prevent jank in CSS and JavaScript?

Optimizing scroll-linked animations requires auditing compositor property usage and ensuring scroll events avoid blocking the main thread. Fixing animation performance targets these issues by enforcing rendering step priorities and converting scroll handlers to efficient transforms.

What is the best way to audit blur effects and transform properties for rendering performance?

The best way to audit blur effects and transform properties is to analyze rendering step priorities and identify inefficient property usage. This animation performance audit checks for compositor-friendly properties and flags never patterns that cause visual jank.

Does this approach to fixing animation jank work with GSAP and WAAPI?

Yes, this approach to fixing animation jank applies to WAAPI, GSAP, CSS, and requestAnimationFrame animations. It audits targeted code to ensure optimal transform and opacity properties are used across these specific JavaScript and CSS animation frameworks.

How do I diagnose a choppy modal transition in my web interface?

Diagnosing a choppy modal transition involves auditing the animation for layout thrashing and inefficient compositor property usage. The process provides concrete code-level suggestions to optimize transform and opacity properties, resolving the visual stuttering.
