边框
用于控制元素轮廓宽度的工具。
¥Basic usage
¥Setting the outline width
使用 outline-*
工具更改元素轮廓的宽度。
¥Use the outline-*
utilities to change the width of an element’s outline.
outline-1
outline-2
outline-4
<button class="outline outline-offset-2 outline-1 ...">Button A</button>
<button class="outline outline-offset-2 outline-2 ...">Button B</button>
<button class="outline outline-offset-2 outline-4 ...">Button C</button>
默认轮廓宽度为 3px
。
¥The default outline width is 3px
.
Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:outline-2
to only apply the outline-2
utility on hover.
<div class="outline hover:outline-2">
<!-- ... -->
</div>
For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.
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-2
to apply the outline-2
utility at only medium screen sizes and above.
<div class="outline md:outline-2">
<!-- ... -->
</div>
To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.
¥Using custom values
¥Customizing your theme
你可以通过编辑 tailwind.config.js
文件中的 theme.outlineWidth
或 theme.extend.outlineWidth
来自定义 outline-*
工具。
¥You can customize the outline-*
utilities by editing theme.outlineWidth
or theme.extend.outlineWidth
in your tailwind.config.js
file.
module.exports = {
theme: {
extend: {
outlineWidth: {
5: '5px',
}
}
}
}

¥Learn more about customizing the default theme in the theme customization documentation.
¥Arbitrary values
If you need to use a one-off outline-width
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="outline-[5px]">
<!-- ... -->
</div>
