+title: <svelte:fragment>
+---
+
+The `<svelte:fragment>` element allows you to add content to a named slot without breaking the document's flow layout.
+
+In the example notice how we applied a flex layout with a gap of 2em to the box.
+
+```sv
+<!-- Box.svelte -->
+<style>
+	.box {
+		width: 300px;
+		border: 1px solid #aaa;
+		border-radius: 2px;
+		box-shadow: 2px 2px 8px rgba(0,0,0,0.1);
+		padding: 1em;
+		margin: 0 0 1em 0;
+		
+		display: flex;
+		flex-direction: column;
+		gap: 1em;
+	}
+</style>
+
+<div class="box">
+	<slot name="header">No header was provided</slot>
+	<p>Some content between header and footer</p>
+	<slot name="footer"></slot>
+</div>
+```
+
+The content in the footer however is not spaced out according to this rythm because wrapping it in a div created a new flow layout.
+
+We can solve this by changing `<div slot="footer">` in the `App` component:
+
+```sv
+<svelte:fragment slot="footer">
+	<p>All rights reserved.</p>
+	<p>Copyright (c) 2019 Svelte Industries</p>
+</svelte:fragment>
+```
