示例

基础示例

使用 break-before-column 和 break-before-page 等工具类，控制元素之前如何进行分栏或分页：

<!-- [!code classes:break-before-column] -->
<div class="columns-2">
  <p>Well, let me tell you something, ...</p>
  <p class="break-before-column">Sure, go ahead, laugh...</p>
  <p>Maybe we can live without...</p>
  <p>Look. If you think this is...</p>
</div>

响应式设计

使用 md: 等断点变体作为 break-before 工具类的前缀，即可仅在中等及以上屏幕尺寸下应用该工具类：

<div class="break-before-column md:break-before-auto ...">
 <!-- ... -->
</div>
