Combining transitions and animations
Layer transitions and animations together for rich, coordinated UI effects.
Combining transitions and animations is a free Sveltejs Academy lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Sveltejs Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Layered Motion
Combine transition: and animate: for items that fade-in AND smoothly reposition.
Example
A todo list where new items fly in and existing items reorder smoothly.
{#each todos as todo (todo.id)}
<li in:fly={{ y: 20 }} animate:flip>{todo.text}</li>
{/each}Order of Application
Svelte handles concurrent transitions and FLIP animations gracefully.
Avoid Conflict
Transitions affect element opacity/position; animations move them. Both run independently.
Match Durations
Use similar durations for transitions and animations so motion feels coordinated.
Use Custom Easing
Apply the same easing function to both for consistent feel.
Performance Watch
Many concurrent animations on large lists can be expensive. Limit visible items or virtualize.
Pair with Stores
Spring or tweened stores can drive numeric props that change alongside transitions.
Real-World Use
Dashboards, drag-and-drop boards, sortable galleries — anywhere lists evolve over time.
Accessibility
Respect prefers-reduced-motion uniformly across both transitions and animations.
Polish Effect
Coordinated motion drastically increases perceived quality. Worth the work.
Quick Check

Recap
Layer transition: for in/out and animate: for reorder to get rich, polished UI.
