示例
防止父级过度滚动
使用 overscroll-contain 工具类，防止目标区域内的滚动触发父元素滚动，但在支持该效果的操作系统中，滚动超过容器末端时仍保留「回弹」效果：
Well, let me tell you something, funny boy. Y'know that little stamp, the one that says "New York Public Library"? Well that may not mean anything to you, but that means a lot to me. One whole hell of a lot.
Sure, go ahead, laugh if you want to. I've seen your type before: Flashy, making the scene, flaunting convention. Yeah, I know what you're thinking. What's this guy making such a big stink about old library books? Well, let me give you a hint, junior.
Maybe we can live without libraries, people like you and me. Maybe. Sure, we're too old to change the world, but what about that kid, sitting down, opening a book, right now, in a branch at the local library and finding drawings of pee-pees and wee-wees on the Cat in the Hat and the Five Chinese Brothers? Doesn't HE deserve better?
<!-- [!code classes:overscroll-contain] -->
<div class="overscroll-contain ...">Well, let me tell you something, ...</div>防止过度滚动回弹
使用 overscroll-none 工具类，防止目标区域内的滚动触发父元素滚动，同时在滚动超过容器末端时也阻止「回弹」效果：
Well, let me tell you something, funny boy. Y'know that little stamp, the one that says "New York Public Library"? Well that may not mean anything to you, but that means a lot to me. One whole hell of a lot.

<div class="overscroll-none ...">Well, let me tell you something, ...</div>使用默认过度滚动行为
使用 overscroll-auto 工具类，让用户到达主滚动区域边界时可以继续滚动父级滚动区域：
Well, let me tell you something, funny boy. Y'know that little stamp, the one that says "New York Public Library"? Well that may not mean anything to you, but that means a lot to me. One whole hell of a lot.

<div class="overscroll-auto ...">Well, let me tell you something, ...</div>响应式设计
使用 md: 等断点变体作为 overscroll-behavior 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="overscroll-auto md:overscroll-contain ...">
<!-- ... -->
</div>了解如何使用变体，请参阅变体文档。
