示例
基本示例
使用 outline-solid 和 outline-dashed 等工具类来设置元素的轮廓样式：
outline-solid
outline-dashed
outline-dotted
outline-double
<button class="outline-2 outline-offset-2 outline-solid ...">Button A</button><button class="outline-2 outline-offset-2 outline-dashed ...">Button B</button><button class="outline-2 outline-offset-2 outline-dotted ...">Button C</button><button class="outline-3 outline-offset-2 outline-double ...">Button D</button>隐藏轮廓
使用 outline-hidden 工具类可以隐藏元素聚焦时的默认浏览器轮廓，同时在强制颜色模式下仍能保持轮廓的显示：
Try emulating `forced-colors: active` in your developer tools to see the behavior
<input class="focus:border-indigo-600 focus:outline-hidden ..." type="text" />强烈建议在使用此工具类时，为了可访问性而应用你自己的焦点样式。
移除轮廓
使用 outline-none 工具类可以完全移除浏览器默认的焦点轮廓：
<div class="focus-within:outline-2 focus-within:outline-indigo-600 ..."> <textarea class="outline-none ..." placeholder="Leave a comment..." /> <button class="..." type="button">Post</button></div>强烈建议在使用此工具类时，为了可访问性而应用你自己的焦点样式。
响应式设计
Prefix an outline-style utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:
<div class="outline md:outline-dashed ..."> <!-- ... --></div>Learn more about using variants in the variants documentation.
