上一章节使用了一个默认插槽（default slot），该slot直接在组件内显示，有时候你需要对子级进行细分设置，就如这个<ContactCard>。在这种情况下，我们可以使用 命名插槽（named slots）。

在ContactCard.svelte中，给每个标签添加name属性：

<article class="contact-card">
	<h2>
		<slot name="name">
			<span class="missing">Unknown name</span>
		</slot>
	</h2>

	<div class="address">
		<slot name="address">
			<span class="missing">Unknown address</span>
		</slot>
	</div>

	<div class="email">
		<slot name="email">
			<span class="missing">Unknown email</span>
		</slot>
	</div>
</article>

然后把 slot="..." 添加到 <ContactCard> 标签内：

<ContactCard>
	<span slot="name">
		P. Sherman
	</span>

	<span slot="address">
		42 Wallaby Way<br>
		Sydney
	</span>
</ContactCard>

示例代码

• App.svelte

<script>
	import ContactCard from './ContactCard.svelte';
</script>

<ContactCard>
	<span slot="name">
		P. Sherman
	</span>

	<span slot="address">
		42 Wallaby Way<br>
		Sydney
	</span>
</ContactCard>

• ContactCard.svelte

<style>
	.contact-card {
		width: 300px;
		border: 1px solid #aaa;
		border-radius: 2px;
		box-shadow: 2px 2px 8px rgba(0,0,0,0.1);
		padding: 1em;
	}

	h2 {
		padding: 0 0 0.2em 0;
		margin: 0 0 1em 0;
		border-bottom: 1px solid #ff3e00
	}

	.address, .email {
		padding: 0 0 0 1.5em;
		background:  0 0 no-repeat;
		background-size: 20px 20px;
		margin: 0 0 0.5em 0;
		line-height: 1.2;
	}

	.address { background-image: url(tutorial/icons/map-marker.svg) }
	.email   { background-image: url(tutorial/icons/email.svg) }
	.missing { color: #999 }
</style>

<article class="contact-card">
	<h2>
		<slot name="name">
			<span class="missing">Unknown name</span>
		</slot>
	</h2>

	<div class="address">
		<slot name="address">
			<span class="missing">Unknown address</span>
		</slot>
	</div>

	<div class="email">
		<slot name="email">
			<span class="missing">Unknown email</span>
		</slot>
	</div>
