Overscroll Behavior

Auto

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

Contain

Use overscroll-contain 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.

None

Use overscroll-none 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.

Responsive

To control the overscroll-behavior property at a specific breakpoint, add a {screen}: prefix to any existing overscroll-behavior utility. For example, use md:overscroll-contain to apply the overscroll-contain utility at only medium screen sizes and above.

<div class="overscroll-auto md:overscroll-contain lg:overscroll-none ...">
  <!-- ... -->
</div>

Customizing

Variants

默認情況下, 只有 響應式 的 overscroll-behavior 變化模式 (variants) 會產生。

在 tailwind.config.js 的 variants 區塊中變更 overscrollBehavior 屬性來決定有哪些變化模式會生成。

舉個例子來說，這個設定將會生成 響應式 和 hover 的變化模式。

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       overscrollBehavior: ['responsive', 'hover'],
      }
    }
  }

Disabling

如果你不打算在專案中使用 overscroll-behavior 功能，可以在你的設定檔裡的 corePlugins 屬性中將 overscrollBehavior 設定為 false 來停用功能：

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     overscrollBehavior: false,
    }
  }
