Describe the task
Ask your agent for something this skill covers. It loads transition-sequences automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Transition Sequence Animations
Apply Disney's 12 principles to choreographed multi-step motion.
Principle Application
Squash & Stretch: Each element in sequence can compress/expand independently for organic feel.
Anticipation: Sequence starts with a setup phase. Brief pause or gather before motion begins.
Staging: Direct attention through the sequence. Most important element animates first or last.
Straight Ahead vs Pose-to-Pose: Plan keyframes for each step. Map the entire sequence before implementing.
Follow Through & Overlapping: Elements don't move in unison. Stagger starts by 50-100ms. Let motion cascade.
Slow In/Slow Out: Each step eases. The sequence overall should ease too - faster middle, slower ends.
Arcs: Transitions across space follow arcs. Page sliding left curves slightly, not linear slide.
Secondary Action: Primary transition + secondary details. Page slides while elements within fade/scale.
Timing:
- Step overlap: 30-50% of previous step's duration
- Total sequence: 300-800ms for UI, up to 1500ms for dramatic
- Gap between steps: 0-100ms (overlap preferred)
Exaggeration: Sequence itself is exaggeration. Individual steps stay subtle.
Solid Drawing: Maintain spatial consistency. If A goes left, B should come from left.
Appeal: Sequences tell a story. Beginning, middle, end - satisfying resolution.
Timing Recommendations
| Sequence Type | Total Duration | Step Count | Step Overlap |
|---|---|---|---|
| Tab Change | 300ms | 2 | 50% |
| Page Transition | 500-600ms | 2-3 | 30% |
| Modal Open | 400ms | 3 | 40% |
| Wizard Step | 400ms | 2 | 50% |
| Onboarding | 800-1200ms | 4-6 | 30% |
| Dramatic Reveal | 1000-1500ms | 5-8 | 40% |
Implementation Patterns
/* Staggered sequence */
.sequence-item {
opacity: 0;
transform: translateY(20px);
animation: reveal 400ms ease-out forwards;
}
.sequence-item:nth-child(1) { animation-delay: 0ms; }
.sequence-item:nth-child(2) { animation-delay: 80ms; }
.sequence-item:nth-child(3) { animation-delay: 160ms; }
.sequence-item:nth-child(4) { animation-delay: 240ms; }
@keyframes reveal {
to {
opacity: 1;
transform: translateY(0);
}
}
/* Page transition choreography */
.page-exit {
animation: page-out 250ms ease-in forwards;
}
.page-enter {
animation: page-in 300ms ease-out 200ms forwards;
}
@keyframes page-out {
to { opacity: 0; transform: translateX(-30px); }
}
@keyframes page-in {
from { opacity: 0; transform: translateX(30px); }
to { opacity: 1; transform: translateX(0); }
}
Sequence Orchestration Formula
// Calculate stagger delays
const items = document.querySelectorAll('.sequence-item');
const totalDuration = 600; // ms
const overlap = 0.4; // 40% overlap
items.forEach((item, index) => {
const stepDuration = totalDuration / items.length;
const delay = index * stepDuration * (1 - overlap);
item.style.animationDelay = `${delay}ms`;
});
Key Rules
- Overlap steps 30-50% - no gaps, no simultaneous starts
- Total sequence under 800ms for functional UI
- Test at 0.5x speed to verify choreography
- Provide skip option for sequences over 500ms

FAQ
What does the transition-sequences skill do?
Use when orchestrating multi-step animations - page transitions, onboarding flows, wizard steps, complex reveals, or any choreographed animation sequence.
How do I install transition-sequences?
Run npx skills add https://github.com/dylantarre/animation-principles --skill transition-sequences in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/transition-sequences/ (personal) or .claude/skills/transition-sequences/ (project).
Which AI agents can use transition-sequences?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is transition-sequences safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
