轮廓颜色

​基本用法

¥Basic usage

​设置轮廓颜色

¥Setting the outline color

使用 outline-* 工具更改元素轮廓的颜色。

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

<button class="outline outline-offset-2 outline-blue-500 ...">Button A</button>
<button class="outline outline-offset-2 outline-cyan-500 ...">Button B</button>
<button class="outline outline-offset-2 outline-pink-500 ...">Button C</button>

​改变透明度

¥Changing the opacity

使用颜色透明度修饰符来控制元素轮廓颜色的透明度。

¥Use the color opacity modifier to control the opacity of an element’s outline color.

<button class="outline-2 outline-blue-500/50 ...">Save Changes</button>

你可以使用 透明度比例 中定义的任何值，或者如果你需要偏离你的设计令牌，则可以使用任意值。

¥You can use any value defined in your opacity scale, or use arbitrary values if you need to deviate from your design tokens.

<button class="outline-4 outline-pink-400/[.55] ..."></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-blue-400 to only apply the outline-blue-400 utility on hover.

<button class="outline hover:outline-blue-400">
  <!-- ... -->
</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-blue-400 to apply the outline-blue-400 utility at only medium screen sizes and above.

<button class="outline md:outline-blue-400">
  <!-- ... -->
</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

By default, Tailwind makes the entire default color palette available as outline colors. You can customize your color palette by editing theme.colors or theme.extend.colors in your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      colors: {
        'regal-blue': '#243c5a',
      },
    }
  }
}

Alternatively, you can customize just your outline colors by editing theme.outlineColor or theme.extend.outlineColor in your tailwind.config.js file.

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-color 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-[#243c5a]">
  <!-- ... -->
</button>

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