Part 2 / Transitions / Adding parameters

Transition functions can accept parameters. Replace the fade transition with fly...

App.svelte
<script>
	import { fly } from 'svelte/transition';
	let visible = true;
</script>

...and apply it to the <p> along with some options:

App.svelte
<p transition:fly={{ y: 200, duration: 2000 }}>
	Flies in and out
</p>

Note that the transition is reversible — if you toggle the checkbox while the transition is ongoing, it transitions from the current point, rather than the beginning or the end.

Next: In and out
