基本用法

¥Basic usage

单边加边距

¥Add margin to a single side

使用 mt-*mr-*mb-*ml-* 工具来控制元素一侧的边距。

¥Use the mt-*, mr-*, mb-*, and ml-* utilities to control the margin on one side of an element.

例如,mt-6 会在元素的顶部添加 1.5rem 的边距,mr-4 会在元素的右侧添加 1rem 的边距,mb-8 会在元素的底部添加 2rem 的边距,ml-2 会在元素的底部添加 0.5rem 的边距 元素的左边。

¥For example, mt-6 would add 1.5rem of margin to the top of an element, mr-4 would add 1rem of margin to the right of an element, mb-8 would add 2rem of margin to the bottom of an element, and ml-2 would add 0.5rem of margin to the left of an element.

mt-6
mr-4
mb-8
ml-2
<div class="mt-6 ...">mt-6</div>
<div class="mr-4 ...">mr-4</div>
<div class="mb-8 ...">mb-8</div>
<div class="ml-2 ...">ml-2</div>

添加水平边距

¥Add horizontal margin

使用 mx-* 工具来控制元素的水平边距。

¥Use the mx-* utilities to control the horizontal margin of an element.

mx-8
<div class="mx-8 ...">mx-8</div>

添加垂直边距

¥Add vertical margin

使用 my-* 工具来控制元素的垂直边距。

¥Use the my-* utilities to control the vertical margin of an element.

my-8
<div class="my-8 ...">my-8</div>

为所有边添加边距

¥Add margin to all sides

使用 m-* 工具来控制元素所有边的边距。

¥Use the m-* utilities to control the margin on all sides of an element.

m-8
<div class="m-8 ...">m-8</div>

使用负值

¥Using negative values

要使用负边距值,请在类名称前加上破折号以将其转换为负值。

¥To use a negative margin value, prefix the class name with a dash to convert it to a negative value.

-mt-8
<div class="w-36 h-16 bg-sky-400 opacity-20 ..."></div>
<div class="-mt-8 bg-sky-300 ...">-mt-8</div>

使用逻辑属性

¥Using logical properties

使用 ms-*me-* 工具设置 margin-inline-startmargin-inline-end 逻辑属性,它们根据文本方向映射到左侧或右侧。

¥Use the ms-* and me-* utilities to set the margin-inline-start and margin-inline-end logical properties, which map to either the left or right side based on the text direction.

Left-to-right

ms-8
me-8

Right-to-left

ms-8
me-8
<div dir="ltr">
  <div class="ms-8 ...">ms-8</div>
  <div class="me-8 ...">me-8</div>
<div>

<div dir="rtl">
  <div class="ms-8 ...">ms-8</div>
  <div class="me-8 ...">me-8</div>
<div>

要获得更多控制,你还可以使用 LTR 和 RTL 修饰符 根据当前文本方向有条件地应用特定样式。

¥For more control, you can also use the LTR and RTL modifiers to conditionally apply specific styles depending on the current text direction.


有条件地应用

悬停、聚焦和其他状态

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:mt-8 仅在 hover 时应用 mt-8 工具。

<div class="mt-4 hover:mt-8">
  <!-- ... -->
</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:mt-8 仅在中等屏幕尺寸及以上时应用 mt-8 工具。

<div class="mt-4 md:mt-8">
  <!-- ... -->
</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 的保证金比例使用 默认间距比例。你可以通过编辑 tailwind.config.js 文件中的 theme.spacingtheme.extend.spacing 来自定义间距比例。

¥By default, Tailwind’s margin scale uses the default spacing scale. You can customize your spacing scale by editing theme.spacing or theme.extend.spacing in your tailwind.config.js file.

tailwind.config.js
module.exports = {
  theme: {
    extend: {
      spacing: {
        '5px': '5px',
      }
    }
  }
}

或者,你可以通过编辑 tailwind.config.js 文件中的 theme.margintheme.extend.margin 来自定义边距比例。

¥Alternatively, you can customize just the margin scale by editing theme.margin or theme.extend.margin in your tailwind.config.js file.

tailwind.config.js
module.exports = {
  theme: {
    extend: {
      margin: {
        '5px': '5px',
      }
    }
  }
}

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

任意值

¥Arbitrary values

如果你需要使用一次性的 margin 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="m-[5px]">
  <!-- ... -->
</div>
