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?
<div class="overscroll-contain ...">是这样的，我说你这滑稽的小家伙，...</div>
阻止过度滚动回弹
使用 overscroll-none 实用工具来阻止目标区域的滚动触发父元素的滚动，并阻止滚动超出容器末端时的“回弹”效果：

使用默认的过度滚动行为
当用户到达主要滚动区域的边界时，使用 overscroll-auto 实用工具使其能够继续滚动父滚动区域：

响应式设计
使用断点变体（例如 md:）作为 overscroll-behavior 实用工具的前缀，以便仅在中等尺寸及以上的屏幕上应用该实用工具：
<div class="overscroll-auto md:overscroll-contain ...">
<!-- ... -->
</div>
在 变体文档 中了解更多关于使用变体的信息。
