CSS scroll-snap-type 屬性指定滾動容器如何捕捉到捕捉位置。

要使用scroll-snap-type 屬性，需要將其設定在滾動容器上。還需要在要捕捉到位元素上設定scroll-snap-align 屬性。

可能的值

  • none − 滾動容器不會捕捉到任何位置。

  • x − 此值用於水平滾動。

  • y − 此值用於垂直滾動。

  • block − 這使得滾動容器停在塊軸上最近的捕捉點。

  • inline − 這使得滾動容器停在內聯軸上最近的捕捉點。

  • both − 指定滾動應該在滾動容器內水平和垂直方向都捕捉。

  • mandatory − 滾動容器應捕捉到最近的捕捉點，這使得使用者必須滾動到特定位置。

  • proximity − 滾動容器應根據接近程度捕捉到最近的捕捉點。

應用於

所有 HTML 元素。

DOM 語法

object.style.scrollSnapType = "none|x|y|block|inline|both|mandatory|proximity";

CSS Scroll Snap Type - None 值

以下示例演示了scroll-snap-type: none 屬性的使用 −

<head>
<style>
   .scroll-container {
      display: flex;
      width: 350px;
      height: 200px;
      overflow-x: scroll;
      overflow-y: hidden;
      white-space: nowrap;
      scroll-snap-type: none;
   }
   .scrolling-section1,
   .scrolling-section2,
   .scrolling-section3 {
      flex: 0 0 auto;
      width: 320px;
      height: 200px;
      scroll-snap-align: center;
   }
