title: Transition events
---

It can be useful to know when transitions are beginning and ending. Svelte dispatches events that you can listen to like any other DOM event:

```html
<p
	transition:fly="{{ y: 200, duration: 2000 }}"
	on:introstart="{() => status = 'intro started'}"
	on:outrostart="{() => status = 'outro started'}"
	on:introend="{() => status = 'intro ended'}"
	on:outroend="{() => status = 'outro ended'}"
>
	Flies in and out
</p>
```
