轮廓偏移

​基本用法

¥Basic usage

​设置轮廓偏移

¥Setting the outline offset

使用 outline-* 工具更改元素轮廓的偏移量。

¥Use the outline-* utilities to change the offset of an element’s outline.

<button class="outline outline-offset-0 ...">Button A</button>
<button class="outline outline-offset-2 ...">Button B</button>
<button class="outline outline-offset-4 ...">Button C</button>

​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:outline-offset-2 to only apply the outline-offset-2 utility on hover.

<button class="outline hover:outline-offset-2">
  <!-- ... -->
</button>

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:outline-offset-2 to apply the outline-offset-2 utility at only medium screen sizes and above.

<button class="outline md:outline-offset-2">
  <!-- ... -->
</button>

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

你可以通过编辑 tailwind.config.js 文件中的 theme.outlineOffset 或 theme.extend.outlineOffset 来自定义 outline-offset-* 工具。

¥You can customize the outline-offset-* utilities by editing theme.outlineOffset or theme.extend.outlineOffset in your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      outlineOffset: {
        3: '3px',
      }
    }
  }
}

¥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 outline-offset 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.

<button class="outline-offset-[3px]">
  <!-- ... -->
</button>
