行高

​基本用法

¥Basic usage

​相对行高

¥Relative line-heights

使用 leading-none、leading-tight、leading-snug、leading-normal、leading-relaxed 和 leading-loose 工具根据元素的当前字体大小为元素提供相对行高。

¥Use the leading-none, leading-tight, leading-snug, leading-normal, leading-relaxed, and leading-loose utilities to give an element a relative line-height based on its current font-size.

<p class="leading-normal ...">So I started to walk into the water...</p>
<p class="leading-relaxed ...">So I started to walk into the water...</p>
<p class="leading-loose ...">So I started to walk into the water...</p>

​固定行高

¥Fixed line-heights

使用 leading-6 和 leading-7 等工具为元素提供固定的行高，而不管当前的字体大小如何。当你需要非常精确地控制元素的最终大小时，这些非常有用。

¥Use utilities like leading-6 and leading-7 to give an element a fixed line-height, irrespective of the current font-size. These are useful when you need very precise control over an element’s final size.

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

​有条件地应用

​悬停、聚焦和其他状态

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:leading-loose to only apply the leading-loose utility on hover.

<p class="leading-none hover:leading-loose">
  <!-- ... -->
</p>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

​断点和媒体查询

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:leading-loose to apply the leading-loose utility at only medium screen sizes and above.

<p class="leading-none md:leading-loose">
  <!-- ... -->
</p>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

​覆盖默认行高

¥Overriding default line-heights

请务必注意，默认情况下，Tailwind 的 font-size 工具各自设置自己的默认行高。这意味着任何时候你使用像 sm:text-xl 这样的响应式字体大小工具，你为较小的断点设置的任何显式行高都将被覆盖。

¥It’s important to note that by default, Tailwind’s font-size utilities each set their own default line-height. This means that any time you use a responsive font-size utility like sm:text-xl, any explicit line-height you have set for a smaller breakpoint will be overridden.

<!-- The `leading-loose` class will be overridden at the `md` breakpoint -->
<p class="text-lg leading-loose md:text-xl">
  Maybe we can live without libraries...
</p>

如果要在设置断点特定的字体大小后覆盖默认行高，请确保也设置断点特定的行高：

¥If you want to override the default line-height after setting a breakpoint-specific font-size, make sure to set a breakpoint-specific line-height as well:

<!-- The `leading-loose` class will be overridden at the `md` breakpoint -->
<p class="text-lg leading-loose md:text-xl md:leading-loose">
  Maybe we can live without libraries...
</p>

在不同的字体大小上使用相同的行高通常不会给你带来好的排版效果。行高通常应该随着字体大小的增加而变小，因此这里的默认行为通常可以为你节省大量工作。如果你发现自己在与它作斗争，你总是可以 自定义你的字体大小比例 不包括默认行高。

¥Using the same line-height across different font sizes is generally not going to give you good typographic results. Line-height should typically get smaller as font-size increases, so the default behavior here usually saves you a ton of work. If you find yourself fighting it, you can always customize your font-size scale to not include default line-heights.

​使用自定义值

¥Using custom values

​自定义主题

¥Customizing your theme

默认情况下，Tailwind 提供六个相对的和八个固定的 line-height 工具。你可以通过自定义 Tailwind 主题配置的 lineHeight 部分来更改、添加或删除这些内容。

¥By default, Tailwind provides six relative and eight fixed line-height utilities. You change, add, or remove these by customizing the lineHeight section of your Tailwind theme config.

module.exports = {
  theme: {
    extend: {
      lineHeight: {
        'extra-loose': '2.5',
        '12': '3rem',
      }
    }
  }
}

在 主题定制 文档中了解有关自定义默认主题的更多信息。

¥Learn more about customizing the default theme in the theme customization documentation.

​任意值

¥Arbitrary values

If you need to use a one-off line-height value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<p class="leading-[3rem]">
  <!-- ... -->
</p>

Learn more about arbitrary value support in the arbitrary values documentation.
