基本用法

¥Basic usage

防止父级过度滚动

¥Preventing parent overscrolling

使用 overscroll-contain 工具可防止目标区域中的滚动触发父元素中的滚动，但在支持它的操作系统中滚动超过容器末尾时保留 “bounce” 效果。

¥Use the overscroll-contain utility to prevent scrolling in the target area from triggering scrolling in the parent element, but preserve “bounce” effects when scrolling past the end of the container in operating systems that support it.

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 ...">Well, let me tell you something, ...</div>

防止过度滚动弹跳

¥Preventing overscroll bouncing

使用 overscroll-none 工具可以防止目标区域中的滚动触发父元素中的滚动，并且还可以防止滚动超过容器末尾时出现 “bounce” 效果。

¥Use the overscroll-none utility to prevent scrolling in the target area from triggering scrolling in the parent element, and also prevent “bounce” effects when scrolling past the end of the container.

<div class="overscroll-none ...">Well, let me tell you something, ...</div>

使用默认的过度滚动行为

¥Using the default overscroll behavior

使用 overscroll-auto 工具使用户可以在到达主滚动区域的边界时继续滚动父滚动区域。

¥Use the overscroll-auto utility to make it possible for the user to continue scrolling a parent scroll area when they reach the boundary of the primary scroll area.

<div class="overscroll-auto ...">Well, let me tell you something, ...</div>

有条件地应用

悬停、聚焦和其他状态

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use focus:overscroll-contain to only apply the overscroll-contain utility on focus.

<html class="overscroll-auto focus:overscroll-contain">
  <!-- ... -->
</html>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

断点和媒体查询

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:overscroll-contain to apply the overscroll-contain utility at only medium screen sizes and above.

<html class="overscroll-auto md:overscroll-contain">
  <!-- ... -->
</html>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.
