+title: Slot props
+---
+
+In this app, we have a `<Hoverable>` component that tracks whether the mouse is currently over it. It needs to pass that data *back* to the parent component, so that we can update the slotted contents.
+
+For this, we use *slot props*. In `Hoverable.svelte`, pass the `hovering` value into the slot:
+
+```html
+<div on:mouseenter={enter} on:mouseleave={leave}>
+	<slot hovering={hovering}></slot>
+</div>
+```
+
+> Remember you can also use the `{hovering}` shorthand, if you prefer.
+
+Then, to expose `hovering` to the contents of the `<Hoverable>` component, we use the `let` directive:
+
+```html
+<Hoverable let:hovering={hovering}>
+	<div class:active={hovering}>
+		{#if hovering}
+			<p>I am being hovered upon.</p>
+		{:else}
+			<p>Hover over me!</p>
+		{/if}
+	</div>
+</Hoverable>
+```
+
+You can rename the variable, if you want — let's call it `active` in the parent component:
+
+```html
+<Hoverable let:hovering={active}>
+	<div class:active>
+		{#if active}
+			<p>I am being hovered upon.</p>
+		{:else}
+			<p>Hover over me!</p>
+		{/if}
+	</div>
+</Hoverable>
+```
+
+You can have as many of these components you like, and the slotted props will remain local to the component where they're declared.
+
+> Named slots can also have props; use the `let` directive on an element with a `slot="..."` attribute, instead of on the component itself.
