title: Adding parameters
---
Transition functions can accept parameters. Replace the `fade` transition with `fly`...
```svelte
<script>
import { fly } from 'svelte/transition';
let visible = true;
</script>
```
...and apply it to the `<p>` along with some options:
```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.
