尺寸

​基本用法

¥Basic usage

​固定尺寸

¥Fixed sizes

使用 size-px、size-1 和 size-64 等工具同时将元素设置为固定宽度和高度。

¥Use utilities like size-px, size-1, and size-64 to set an element to a fixed width and height at the same time.

<div class="size-16 ...">size-16</div>
<div class="size-20 ...">size-20</div>
<div class="size-24 ...">size-24</div>
<div class="size-32 ...">size-32</div>
<div class="size-40 ...">size-40</div>

​百分比大小

¥Percentage sizes

使用 size-full 将元素的宽度和高度设置为父容器宽度和高度的 100%。

¥Use size-full to set an element’s width and height to be 100% of the parent container’s width and height.

<div class="h-56 p-2 ...">
  <div class="size-full ...">size-full</div>
</div>

​重置尺寸

¥Resetting the size

如果你需要在特定条件下（例如在特定断点处）删除元素指定的宽度和高度，则 size-auto 工具会很有用：

¥The size-auto utility can be useful if you need to remove an element’s assigned width and height under a specific condition, like at a particular breakpoint:

<div class="size-full md:size-auto">
  <!-- ... -->
</div>

​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:size-full to only apply the size-full utility on hover.

<div class="size-48 hover:size-full">
  <!-- ... -->
</div>

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:size-full to apply the size-full utility at only medium screen sizes and above.

<div class="size-48 md:size-full">
  <!-- ... -->
</div>

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

​使用自定义值

¥Using custom values

​自定义主题

¥Customizing your theme

默认情况下，Tailwind 的尺寸比例是 默认间距比例 以及一些特定于尺寸的附加值的组合。

¥By default, Tailwind’s size scale is a combination of the default spacing scale as well as some additional values specific to sizing.

你可以通过编辑 tailwind.config.js 文件中的 theme.spacing 或 theme.extend.spacing 来自定义间距比例。

¥You can customize your spacing scale by editing theme.spacing or theme.extend.spacing in your tailwind.config.js file.

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

要单独自定义大小，请使用 tailwind.config.js 文件的 theme.size 部分。

¥To customize size separately, use the theme.size section of your tailwind.config.js file.

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

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 size 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.

<div class="size-[32rem]">
  <!-- ... -->
</div>

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