Production-ready animation patterns for React / Next.js — button, modal, toast, stagger, page transitions, exit animations, scroll, and layout — built on motion-foundations tokens and springs. Use when animating a specific UI element in React or Next.js — button, modal, toast, stagger, page transition, or scroll.

Motion Patterns

Copy-paste patterns for the most common UI animation needs. Every pattern here is built on motion-foundations tokens and springs. Do not define new duration or easing values here — import them.

When to Activate

Animating a button, card, modal, or toast notification
Building list entrances with stagger
Setting up page transitions in Next.js App Router
Adding entrance or exit animations to conditional content
Implementing scroll-reveal, scroll-linked progress, or sticky story sections
Building expanding cards, accordions, or shared-element transitions

Outputs

This skill produces:

Accessible, SSR-safe animation for all standard UI components
AnimatePresence-wrapped conditional renders with correct exit behavior
Page transition wrapper component for Next.js App Router
Scroll-reveal and scroll-linked patterns using useScroll + useTransform
Layout animation patterns (layout, layoutId) for expanding and crossfading elements

Principles

Every pattern imports from motion-foundations. No raw numbers.
Every conditional render is wrapped in AnimatePresence with a key.
Exit animations are always defined alongside enter animations — never as an afterthought.
layout is used only for small, isolated shifts. Large subtrees get explicit transforms.

Rules

Always wrap conditional renders in AnimatePresence with a key on the direct child. Without a key, exit animations never fire.
Always define exit when defining initial + animate. An animation without an exit is incomplete.
Use mode="wait" on page transitions. Enter must not start until exit completes.
Never use layout on subtrees with more than ~5 children or deeply nested DOM. Use explicit x/y transforms instead.
Stagger interval must stay between 0.05s and 0.10s. Below feels mechanical; above feels sluggish.
Modals must always include: focus trap, Escape-key close, scroll lock, role="dialog", aria-modal="true".
Scroll reveals use viewport={{ once: true }}. Repeating on scroll-out is distracting, not informative.
All token values are imported from motion-foundations. No inline numbers.

Decision Guidance

Choosing the right pattern

Situation	Pattern
Element appears / disappears	`AnimatePresence`
List of items loading in sequence	Stagger variants
Navigating between routes	Page transition wrapper
Element changes size in place	`layout` prop
Same element moves across page contexts	`layoutId`
Element enters when scrolled into view	`whileInView`
Value tied to scroll position	`useScroll` + `useTransform`

When to use `mode="wait"` vs `mode="sync"`

Mode	Use when
`wait`	Page transitions, content swaps (one at a time)
`sync`	Stacked notifications, list items (overlap is fine)
`popLayout`	Items removed from a reflow list

Core Concepts

AnimatePresence contract

Three things must always be true:

AnimatePresence wraps the conditional
The direct child has a key
The child has an exit prop

Miss any one of these and the exit animation silently fails.

layout vs layoutId

layout — animates the element's own size/position change in place
layoutId — links two separate elements, crossfading between them across renders

Use layout="position" on text inside an expanding container to prevent text reflow from animating.

  )
}

Shared-element crossfade

// Source context
<motion.img layoutId="hero-image" src={src} className="w-16 h-16 rounded" />
 
// Destination context (same layoutId — motion handles the transition)
<motion.img layoutId="hero-image" src={src} className="w-full rounded-xl" />

  transition={{
    duration: motionTokens.duration.normal,
    ease: motionTokens.easing.smooth,
  }}
> {children}
</motion.div>

End-to-End Example

A staggered list that enters on mount, handles conditional presence, and respects reduced motion — combining tokens, springs, AnimatePresence, and the accessibility hook from motion-foundations:

"use client"
import { useState } from "react"
import { motion, AnimatePresence } from "motion/react"
import { motionTokens, springs } from "@/lib/motion-tokens"
import { useSafeMotion } from "@/hooks/use-reduced-motion"
 
const containerVariants = {
  hidden: {},
  visible: {
    transition: { staggerChildren: 0.08, delayChildren: 0.1 },
  },
}
 
function ListItem({ label, onRemove }: { label: string; onRemove: () => void }) {
  const safe = useSafeMotion(motionTokens.distance.sm)
  return (
    <motion.li
      variants={{
        hidden:  safe.initial,
        visible: safe.animate,
      }}
      exit={safe.exit}
      transition={springs.gentle}
      className="flex items-center justify-between p-3 rounded-lg bg-white shadow-sm"
    >
      <span>{label}</span>
      <button onClick={onRemove}>Remove</button>
    </motion.li>
  )
}
 
export function AnimatedList({ items, onRemove }: {
  items: { id: string; label: string }[]
  onRemove: (id: string) => void
}) {
  return (
    <motion.ul
      variants={containerVariants}
      initial="hidden"
      animate="visible"
      className="space-y-2"
    >
      <AnimatePresence mode="popLayout">
        {items.map((item) => (
          <ListItem
            key={item.id}
            label={item.label}
            onRemove={() => onRemove(item.id)}
          />
        ))}
      </AnimatePresence>
    </motion.ul>
  )
}

Constraints / Non-Goals

This skill does not cover:

Token and spring definitions → see motion-foundations
Drag interactions, swipe gestures, reorderable lists → see motion-advanced
Text animations (word/character reveal, counters) → see motion-advanced
SVG path drawing or morphing → see motion-advanced
Custom animation hooks → see motion-advanced
CSS-only transitions not using motion/react

Anti-Patterns

Anti-pattern	Rule violated	Fix
`AnimatePresence` child missing `key`	Rule 1	Add stable `key` to the direct child
`initial` + `animate` without `exit`	Rule 2	Always define all three together
Page transition without `mode="wait"`	Rule 3	Add `mode="wait"` to `AnimatePresence`
`layout` on a 50-item list	Rule 4	Use `mode="popLayout"` or explicit transforms
`staggerChildren: 0.2` on a 10-item list	Rule 5	Cap at `0.08–0.10`
Modal without focus trap	Rule 6	Add `focus-trap-react` or Radix Dialog
`whileInView` without `viewport={{ once: true }}`	Rule 7	Repeating entrances distract, not inform
`transition={{ duration: 0.3 }}` inline	Rule 8	Use `motionTokens.duration.normal`

motion-foundations — defines all tokens, springs, the useSafeMotion hook, and SSR guards that every pattern here imports. Must be set up first.
motion-advanced — extends these patterns with drag, gestures, SVG, text, custom hooks, and imperative sequencing. Does not redefine any patterns from this skill.

Constraints / Non-Goals

This skill does not cover:

Token and spring definitions → see motion-foundations
Drag interactions, swipe gestures, reorderable lists → see motion-advanced
Text animations (word/character reveal, counters) → see motion-advanced
SVG path drawing or morphing → see motion-advanced
Custom animation hooks → see motion-advanced
CSS-only transitions not using motion/react

Anti-Patterns

Anti-pattern	Rule violated	Fix
`AnimatePresence` child missing `key`	Rule 1	Add stable `key` to the direct child
`initial` + `animate` without `exit`	Rule 2	Always define all three together
Page transition without `mode="wait"`	Rule 3	Add `mode="wait"` to `AnimatePresence`
`layout` on a 50-item list	Rule 4	Use `mode="popLayout"` or explicit transforms
`staggerChildren: 0.2` on a 10-item list	Rule 5	Cap at `0.08–0.10`
Modal without focus trap	Rule 6	Add `focus-trap-react` or Radix Dialog
`whileInView` without `viewport={{ once: true }}`	Rule 7	Repeating entrances distract, not inform
`transition={{ duration: 0.3 }}` inline	Rule 8	Use `motionTokens.duration.normal`

motion-foundations — defines all tokens, springs, the useSafeMotion hook, and SSR guards that every pattern here imports. Must be set up first.
motion-advanced — extends these patterns with drag, gestures, SVG, text, custom hooks, and imperative sequencing. Does not redefine any patterns from this skill.
