Special elements / <svelte:head> • Svelte Tutorial

Advanced Svelte Special elements <svelte:head>

The <svelte:head> element allows you to insert elements inside the <head> of your document. This is useful for things like <title> and <meta> tags, which are critical for good SEO.

Since those are quite hard to show in the context of this tutorial, we’ll use it for a different purpose — loading stylesheets.

App

<script>
	const themes = ['margaritaville', 'retrowave', 'spaaaaace', 'halloween'];
	let selected = $state(themes[0]);
</script>

<svelte:head>
	<link rel="stylesheet" href="/tutorial/stylesheets/{selected}.css" />
</svelte:head>

<h1>Welcome to my site!</h1>

<script lang="ts">
	const themes = ['margaritaville', 'retrowave', 'spaaaaace', 'halloween'];
	let selected = $state(themes[0]);
</script>

<svelte:head>
	<link rel="stylesheet" href="/tutorial/stylesheets/{selected}.css" />
</svelte:head>

<h1>Welcome to my site!</h1>

In server-side rendering (SSR) mode, contents of <svelte:head> are returned separately from the rest of your HTML.
