Built-in Transitions
Svelte ships several transitions in svelte/transition: fade, fly, slide, scale, blur, draw.
Import a Transition
Bring in the ones you need.
import { fade, fly } from "svelte/transition";Attach with transition:
Apply with transition: on an element controlled by {#if}.
{#if visible}
<p transition:fade>Hello</p>
{/if}Fly Transition
The fly transition moves elements from a coordinate offset to position.
{#if visible}
<div transition:fly={{ x: -200, duration: 400 }}>Slide in</div>
{/if}Parameters Object
Pass options like x, y, duration, delay, and easing.
When Triggers Fire
Transitions run on mount and unmount of the element inside {#if}, {#each}, or {#await} blocks.
Combine Transitions
Apply one transition per directive. Use in: and out: for asymmetric.
Smooth UX
Transitions make UI feel polished without writing keyframes manually.
Performance
Built-in transitions use CSS where possible for GPU acceleration.
Reduced Motion
Respect prefers-reduced-motion by conditionally applying transitions.
Easing
Pass an easing function from svelte/easing for fancier motion.
import { cubicOut } from "svelte/easing";
<p transition:fade={{ easing: cubicOut }}>...</p>Quick Check
