You say
Read my tokens.css and generate a staggered fade-in entrance for my feature grid and a hover-lift effect for the pricing cards.
Your agent does
Generated animations/entrance-animations.css with .enter-stagger using your --transition-slow token. Added .hover-lift to animations/hover-effects.css. Use --stagger-index on child elements to trigger the sequence. View the new index.html for a live demo of the effects.

About This Skill
The problem
Static websites feel unfinished and fail to guide user attention. Writing performant, accessible CSS keyframes and stateful transitions from scratch is tedious and often results in inconsistent timing across a project.
What it does
- Generates production-ready CSS for six categories including hover effects, scroll reveals, and loading states.
- Builds stateful UI transition logic for accordions, modals, tabs, and drawers using optimized grid and transform properties.
- Automatically synchronizes motion with your existing design tokens or provides sane fallbacks for colors and timing.
- Includes a lightweight vanilla JS observer for scroll-triggered entrance animations.
Frameworks & tools
Framework-agnostic. Works with React, Vue, Tailwind CSS, or plain HTML. Uses standard CSS custom properties and vanilla JavaScript.
Why this beats prompting it yourself
General LLMs often overlook accessibility and performance. This skill enforces prefers-reduced-motion resets, keyboard-friendly focus states, and hardware-accelerated transforms. It ensures every animation follows consistent easing curves rather than random duration values.
Use cases
- Applying staggered entrance animations to a feature grid or list.
- Adding shimmer skeleton states to content loaders during async data fetching.
- Creating polished hover-lift and glow effects for pricing cards and CTA buttons.
- Implementing accessible, animated navigation drawers and mobile menus.
Known limitations
Requires an IntersectionObserver-compatible browser for scroll-reveal features, though it fails gracefully by showing content statically.
Use Cases
- Convert static UI components into polished, motion-rich interfaces.
- Enforce project-wide consistency using global easing and timing tokens.
- Standardize accessibility with automatic reduced-motion overrides.
- Deploy lightweight scroll-triggered reveals without heavy libraries.
Known Limitations
Scroll reveal requires IntersectionObserver (skipped if unavailable — elements remain visible); color-mix() needs rgba fallback for older browsers; hover effects on touch devices use :active/:focus-visible only; stateful UI transitions (modal, dropdown, drawer, toast) require JS for open/close state management; prefers-reduced-motion uses class-targeted reset (not universal *)
