轮廓颜色

示例

基本示例

使用类似 outline-rose-500 和 outline-lime-100 的工具类控制元素的轮廓颜色：

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

更改不透明度

使用颜色不透明度修饰符控制元素轮廓颜色的不透明度：

<button class="outline-2 outline-blue-500/100 ...">按钮 A</button>
<button class="outline-2 outline-blue-500/75 ...">按钮 B</button>
<button class="outline-2 outline-blue-500/50 ...">按钮 C</button>

使用自定义值

Use the outline-[<value>] syntax to set the 轮廓颜色 based on a completely custom value:

<div class="outline-[#243c5a] ...">
  <!-- ... -->
</div>

For CSS variables, you can also use the outline-(<custom-property>) syntax:

<div class="outline-(--my-color) ...">
  <!-- ... -->
</div>

This is just a shorthand for outline-[var(<custom-property>)] that adds the var() function for you automatically.

响应式设计

Prefix an outline-color utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

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

Learn more about using variants in the variants documentation.

自定义主题

Use the --color-* theme variables to customize the color utilities in your project:

@theme {
  --color-regal-blue: #243c5a; 
}

Now the outline-regal-blue utility can be used in your markup:

<div class="outline-regal-blue">
  <!-- ... -->
</div>
