Similar to `<svelte:window>`, the `<svelte:body>` element allows you to listen for events that fire on `document.body`. This is useful with the `mouseenter` and `mouseleave` events, which don't fire on `window`.
Add the `mouseenter` and `mouseleave` handlers to the `<svelte:body>` tag:
```html
<svelte:body
on:mouseenter={handleMouseenter}
on:mouseleave={handleMouseleave}
/>
```

Similar to `<svelte:window>`, the `<svelte:document>` element allows you to listen for events that fire on `document`. This is useful with events like `selectionchange`, which doesn't fire on `window`.
Add the `selectionchange` handler to the `<svelte:document>` tag:

<svelte:document on:selectionchange={handleSelectionChange} />
```
> Avoid `mouseenter` and `mouseleave` handlers on this element, these events are not fired on `document` in all browsers. Use `<svelte:body>` for this instead.
