We can also bind to certain properties of `window`, such as `scrollY`. Update line 7:

```html
<svelte:window bind:scrollY={y}/>
```

The list of properties you can bind to is as follows:

* `innerWidth`
* `innerHeight`
* `outerWidth`
* `outerHeight`
* `scrollX`
* `scrollY`
* `online` — an alias for `window.navigator.onLine`

All except `scrollX` and `scrollY` are readonly.
