Visible

Use overflow-visible to prevent content within an element from being clipped. Note that any content that overflows the bounds of the element will then be visible.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris eleifend rutrum auctor. Phasellus convallis sagittis augue ut ornare. Vestibulum et gravida lectus, sed ultrices sapien. Nullam aliquet elit dui, vitae hendrerit lectus volutpat eget

<div class="overflow-visible h-24 ...">Lorem ipsum dolor sit amet...</div>

Auto

Use overflow-auto to add scrollbars to an element in the event that its content overflows the bounds of that element. Unlike .overflow-scroll, which always shows scrollbars, this utility will only show them if scrolling is necessary.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris eleifend rutrum auctor. Phasellus convallis sagittis augue ut ornare. Vestibulum et gravida lectus, sed ultrices sapien. Nullam aliquet elit dui, vitae hendrerit lectus volutpat eget. In porttitor tincidunt egestas. Pellentesque laoreet ligula at est vulputate facilisis. Etiam tristique justo ut odio placerat ornare. Cras bibendum, orci at ornare tincidunt, lacus nunc gravida enim, sit amet euismod nunc lectus in lectus. Ut dictum nulla et arcu aliquet ornare. Aliquam et dapibus lectus.

In id felis vulputate, tempor massa eget, malesuada mauris. Quisque fringilla consequat metus, luctus scelerisque leo fringilla vel.

<div class="overflow-auto h-32 ...">Lorem ipsum dolor sit amet...</div>

Hidden

Use overflow-hidden to clip any content within an element that overflows the bounds of that element.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris eleifend rutrum auctor. Phasellus convallis sagittis augue ut ornare. Vestibulum et gravida lectus, sed ultrices sapien. Nullam aliquet elit dui, vitae hendrerit lectus volutpat eget. In porttitor tincidunt egestas. Pellentesque laoreet ligula at est vulputate facilisis. Etiam tristique justo ut odio placerat ornare. Cras bibendum, orci at ornare tincidunt, lacus nunc gravida enim, sit amet euismod nunc lectus in lectus. Ut dictum nulla et arcu aliquet ornare. Aliquam et dapibus lectus. Aenean mattis elit mi, sed ultricies augue consectetur id. Sed id magna malesuada, luctus urna a, bibendum tortor. Cras cursus cursus ex. Nulla fringilla elit vitae imperdiet scelerisque. Donec ac sem eu diam convallis mollis a sed leo. Proin congue augue turpis, eget rutrum dolor ultricies non. Nulla blandit venenatis dapibus. Sed tincidunt mollis elit, quis suscipit nibh eleifend quis. Donec ex lorem, auctor eu rutrum in, blandit id dolor. Nulla molestie arcu turpis. In id felis vulputate, tempor massa eget, malesuada mauris. Quisque fringilla consequat metus, luctus scelerisque leo fringilla vel.

<div class="overflow-hidden h-32 ...">Lorem ipsum dolor sit amet...</div>

Scroll horizontally if needed

Use overflow-x-auto to allow horizontal scrolling if needed.

Scroll vertically if needed

Use overflow-y-auto to allow vertical scrolling if needed.

<div class="overflow-y-auto h-32 ...">Lorem ipsum dolor sit amet...</div>

Scroll horizontally always

Use overflow-x-scroll to allow horizontal scrolling and always show scrollbars unless always-visible scrollbars are disabled by the operating system.

Lorem ipsum dolor sit amet, consectetur adipiscing elit.

<div class="overflow-x-scroll ...">QrLmmW69vMQD...</div>

Scroll vertically always

Use overflow-y-scroll to allow vertical scrolling and always show scrollbars unless always-visible scrollbars are disabled by the operating system.

Lorem ipsum dolor sit amet, consectetur adipiscing elit.

<div class="overflow-y-scroll h-32 ...">Lorem ipsum dolor sit amet...</div>

Scroll in all directions

Use overflow-scroll to add scrollbars to an element. Unlike .overflow-auto, which only shows scrollbars if they are necessary, this utility always shows them. Note that some operating systems (like macOS) hide unnecessary scrollbars regardless of this setting.

<div class="overflow-scroll h-32 ...">Lorem ipsum dolor sit amet...</div>

Responsive

To apply an overflow utility only at a specific breakpoint, add a {screen}: prefix to the existing class name. For example, adding the class md:overflow-scroll to an element would apply the overflow-scroll utility at medium screen sizes and above.

<div class="overflow-auto md:overflow-scroll ...">
  Lorem ipsum dolor sit amet...
</div>

Customizing

Variants

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

tailwind.config.jsvariants 區塊中變更 overflow 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: {
        // ...
+       overflow: ['responsive', 'hover'],
      }
    }
  }

Disabling

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

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