Create performant web animations with proper accessibility and timing.
Create performant web animations with proper accessibility and timing.
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Only these properties animate on the compositor thread (60fps): PropertyUsetransformMove, rotate, scale (translateX, rotate, scale)opacityFade in/out Everything else triggers layout or paint. Avoid animating: width, height, margin, padding (layout thrashing) top, left, right, bottom (use transform instead) border-width, font-size (expensive reflows) /* ❌ Triggers layout every frame */ .slide { left: 100px; transition: left 0.3s; } /* ✅ GPU accelerated */ .slide { transform: translateX(100px); transition: transform 0.3s; }
~5% of users experience vestibular disorders (dizziness, nausea from motion). /* Only animate if user hasn't requested reduced motion */ @media (prefers-reduced-motion: no-preference) { .animated { animation: slide-in 0.5s ease-out; } } /* Or disable for those who requested it */ @media (prefers-reduced-motion: reduce) { *, *::before, *::after { animation-duration: 0.01ms !important; animation-iteration-count: 1 !important; transition-duration: 0.01ms !important; } } Keep subtle fades and color changes even with reduced motion. Remove parallax, bouncing, infinite loops.

Transitions: A to B state changes .button { transform: scale(1); transition: transform 0.2s ease-out; } .button:hover { transform: scale(1.05); } Animations: Multi-step, auto-play, looping @keyframes fadeSlideIn { 0% { opacity: 0; transform: translateY(20px); } 100% { opacity: 1; transform: translateY(0); } } .card { animation: fadeSlideIn 0.5s ease-out forwards; } Use transitions for hover/focus states. Use animations for on-load effects and sequences.
Only use as optimization when you have specific performance problems: /* ✅ Apply before animation starts, remove after */ .card:hover { will-change: transform; } .card { will-change: auto; } /* ❌ Never apply globally */ * { will-change: transform, opacity; } /* Wastes GPU memory */
/* ❌ Animates everything including unintended properties */ .card { transition: all 0.3s; } /* ✅ Only animates what you need */ .card { transition: transform 0.3s, box-shadow 0.3s; } all can cause unexpected animations on color, background, border changes.
Exit animations require AnimatePresence: /* ❌ Exit animation never plays */ {isVisible && <motion.div exit={{ opacity: 0 }} />} /* ✅ Wrap conditional rendering */ <AnimatePresence> {isVisible && <motion.div exit={{ opacity: 0 }} />} </AnimatePresence> Stable keys for list animations: /* ❌ Index keys cause erratic animations */ {items.map((item, i) => <li key={i}>{item}</li>)} /* ✅ Stable IDs */ {items.map(item => <li key={item.id}>{item.text}</li>)} AutoAnimate parent must be unconditional: /* ❌ Ref can't attach to conditional element */ {showList && <ul ref={parent}>...</ul>} /* ✅ Parent always renders, children are conditional */ <ul ref={parent}>{showList && items.map(...)}</ul>
