Use this skill for Browser CSS transitions, keyframes, scroll-driven animations, registered properties, discrete transitions, reduced motion, and performance-safe CSS motion. Trigger on CSS transition, @keyframes, animation-timeline, prefers-reduced-motion, @starting-style, transition-behavior, CSS animation. Do not use for near-miss tasks outside these boundaries; route to adjacent motion or platform skills when they own the implementation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Web CSS Animations Browser CSS transitions, keyframes, scroll-driven animations, registered properties, discrete transitions, reduced motion, and performance-safe CSS motion. ## Operating Contract Use this skill as a compact router plus domain checklist. Load references only when the current task matches their condition. Do not cite local scrape paths, machine cache paths, or hidden source locations. Verify API details against the target repo's installed package versions before editing. ## Source Order 1. Inspect the target repo's installed packages, framework/runtime versions, local design tokens, accessibility policy, and existing motion patterns. 2. Use the bundled references below for skill-specific gotchas and copied source excerpts. 3. Use official current docs/package source as API truth when local code or bundled notes are version-sensitive. ## Decision Boundaries - Use CSS first for two-state UI motion. - Move to WAAPI when an Animation object or seeking is needed. - Move to GSAP for complex imperative choreography. ## Workflow 1. Identify the state driver and animated properties. 2. Use explicit transition-property lists and product motion tokens. …

How to install
mdr add bjornmelin/dev-skills/web-css-animations@sha256:052aadc4ae24d785The line at the top of this page pins the label git:20260608.3feb99e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
