示例

基本示例

使用类似 text-smtext-lg 的实用工具来设置元素的字体大小

text-sm

The quick brown fox jumps over the lazy dog.

text-base

The quick brown fox jumps over the lazy dog.

text-lg

The quick brown fox jumps over the lazy dog.

text-xl

The quick brown fox jumps over the lazy dog.

<p class="text-sm ...">The quick brown fox ...</p>
<p class="text-base ...">The quick brown fox ...</p>
<p class="text-lg ...">The quick brown fox ...</p>
<p class="text-xl ...">The quick brown fox ...</p>
<p class="text-2xl ...">The quick brown fox ...</p>

设置行高

使用类似 text-sm/6text-lg/7 的实用工具来同时设置元素的字体大小和行高

text-sm/6

So I started to walk into the water. I won't lie to you boys, I was terrified. But I pressed on, and as I made my way past the breakers a strange calm came over me. I don't know if it was divine intervention or the kinship of all living things but I tell you Jerry at that moment, I was a marine biologist.

text-sm/7

So I started to walk into the water. I won't lie to you boys, I was terrified. But I pressed on, and as I made my way past the breakers a strange calm came over me. I don't know if it was divine intervention or the kinship of all living things but I tell you Jerry at that moment, I was a marine biologist.

text-sm/8

So I started to walk into the water. I won't lie to you boys, I was terrified. But I pressed on, and as I made my way past the breakers a strange calm came over me. I don't know if it was divine intervention or the kinship of all living things but I tell you Jerry at that moment, I was a marine biologist.

<p class="text-sm/6 ...">So I started to walk into the water...</p>
<p class="text-sm/7 ...">So I started to walk into the water...</p>
<p class="text-sm/8 ...">So I started to walk into the water...</p>

使用自定义值

使用 text-[<value>] 语法 来设置字体大小基于完全自定义的值

<p class="text-[14px] ...">
Lorem ipsum dolor sit amet...
</p>

对于 CSS 变量,你也可以使用 text-(length:<custom-property>) 语法

<p class="text-(length:--my-text-size) ...">
Lorem ipsum dolor sit amet...
</p>

这只是 text-[lengthvar(<custom-property>)] 的简写形式,它会自动为你添加 var() 函数。

响应式设计

前缀一个 font-size 实用工具 带有像 md: 这样的断点变体,以便仅在中等 屏幕尺寸及以上尺寸应用该实用工具

<p class="text-sm md:text-base ...">
Lorem ipsum dolor sit amet...
</p>

了解更多关于在变体文档中使用变体的信息。

自定义你的主题

使用 --text-* 主题变量来自定义字体大小 项目中的实用工具

@theme {
--text-tiny: 0.625rem;
}

现在 text-tiny 实用工具可以在你的标记中使用

<div class="text-tiny">
<!-- ... -->
</div>

你也可以为一个字体大小提供默认的 line-heightletter-spacingfont-weight

@theme {
--text-tiny: 0.625rem;
--text-tiny--line-height: 1.5rem;
--text-tiny--letter-spacing: 0.125rem;
--text-tiny--font-weight: 500;
}
