最大宽度

​基本用法(Basic usage)

​设置最大宽度(Setting the maximum width)

使用 max-w-* 工具设置元素的最大宽度。

🌐 Set the maximum width of an element using the max-w-* utilities.

<div>
  <div class="w-full max-w-96 ...">max-w-96</div>
  <div class="w-full max-w-80 ...">max-w-80</div>
  <div class="w-full max-w-64 ...">max-w-64</div>
  <div class="w-full max-w-48 ...">max-w-48</div>
  <div class="w-full max-w-40 ...">max-w-40</div>
  <div class="w-full max-w-32 ...">max-w-32</div>
  <div class="w-full max-w-24 ...">max-w-24</div>
</div>

​调整大元素的大小(Sizing large elements)

在 24rem 之上，max-w-* 工具使用命名尺度而不是数字尺度，以使数值更容易猜测。

🌐 Above 24rem, the max-w-* utilities use a named scale instead of a numeric scale to make the values easier to guess.

</div>

​阅读宽度(Reading width)

max-w-prose 工具为元素提供经过优化的最大宽度以提高可读性，并会根据字体大小进行适应。

🌐 The max-w-prose utility gives an element a max-width optimized for readability and adapts based on the font size.

<div class="text-sm max-w-prose ...">
  <p>Oh yeah. It's the best part. It's crunchy, it's explosive, it's where the muffin breaks free of the pan and sort of does it's own thing. I'll tell you. That's a million dollar idea right there. Just sell the tops.</p>
</div>

<div class="text-base max-w-prose ...">
  <p>Oh yeah. It's the best part. It's crunchy, it's explosive, it's where the muffin breaks free of the pan and sort of does it's own thing. I'll tell you. That's a million dollar idea right there. Just sell the tops.</p>
</div>

<div class="text-xl max-w-prose ...">
  <p>Oh yeah. It's the best part. It's crunchy, it's explosive, it's where the muffin breaks free of the pan and sort of does it's own thing. I'll tell you. That's a million dollar idea right there. Just sell the tops.</p>
</div>

​限制到你的断点(Constraining to your breakpoints)

max-w-screen-* 类可以用来给元素设置与特定断点匹配的最大宽度。这些值是自动从你的 tailwind.config.js 文件的 theme.screens 部分 中派生的。

🌐 The max-w-screen-* classes can be used to give an element a max-width matching a specific breakpoint. These values are automatically derived from the theme.screens section of your tailwind.config.js file.

<div class="max-w-screen-2xl">
  <!-- ... -->
</div>

​有条件申请

​悬停、聚焦及其他状态

Tailwind 允许你使用变体修饰符在不同状态下有条件地应用工具类。例如，使用hover:max-w-lg 仅在 hover 时应用 max-w-lg 工具。

<div class="max-w-sm hover:max-w-lg">
  <!-- ... -->
</div>

有关所有可用状态修饰符的完整列表，请查看悬停、聚焦、以及其他状态 文档。

​断点和媒体查询

你还可以使用变体修饰符来定位媒体查询，例如响应式断点、暗黑模式、首选减少运动等。例如，使用 md:max-w-lg 仅在中等屏幕尺寸及以上时应用 max-w-lg 工具。

<div class="max-w-sm md:max-w-lg">
  <!-- ... -->
</div>

要了解更多信息，请查看有关 响应式设计、暗黑模式、以及 其他媒体查询修饰符 的文档。

​使用自定义值(Using custom values)

​自定义主题(Customizing your theme)

默认情况下，Tailwind 的最大宽度刻度是 默认间距刻度 与一组额外的用于 大型元素 的命名尺寸的组合，这些尺寸是 max-w-* 工具独有的。

🌐 By default, Tailwind’s maximum width scale is a combination of the default spacing scale as well as an additional set of named sizes for large elements exclusive to the max-w-* utilities.

你可以通过编辑 tailwind.config.js 文件中的 theme.spacing 或 theme.extend.spacing 来自定义全局间距比例的数值。

🌐 You can customize values in the global spacing scale by editing theme.spacing or theme.extend.spacing in your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      spacing: {
        '128': '32rem',
      }
    }
  }
}

要仅为 max-w-* 工具自定义值，请使用 tailwind.config.js 文件中的 theme.maxWidth 部分。

🌐 To customize values for just the max-w-* utilities, use the theme.maxWidth section of your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      maxWidth: {
        '8xl': '96rem',
      }
    }
  }
}

请注意，在 theme.maxWidth 中定义的值优先于在 theme.spacing 中定义的值，因此向 theme.spacing 添加与默认命名尺寸（如 lg 或 xl）匹配的自定义值不会影响相应的 max-w-* 实用程序。

🌐 Note that values defined in theme.maxWidth take precedence over values defined in theme.spacing, so adding a custom value to theme.spacing that matches one of the default named sizes (like lg or xl) will not affect the corresponding max-w-* utility.

module.exports = {
  theme: {
    extend: {
      spacing: {
        'lg': '30rem',
      }
    }
  }
}

module.exports = {
  theme: {
    extend: {
      maxWidth: {
        'lg': '30rem',
      }
    }
  }
}

​任意值(Arbitrary values)

如果你需要使用一次性的 max-width 值，而该值没有必要包含在你的主题中，请使用方括号动态生成属性，使用任意值。

<div class="max-w-[220px]">
  <!-- ... -->
</div>
