Tailwind CSS Scroll Snap 型別類示例

以下是 **Tailwind CSS Scroll Snap 型別** 類的示例，展示了它們如何控制在容器內滾動停止和對齊的特定點。

使用 Tailwind CSS 進行水平滾動捕捉

此示例演示如何使用 Tailwind CSS Scroll Snap 型別類。以下程式碼應用 **snap-x** 類以啟用水平滾動捕捉並設定子元素的滾動捕捉對齊方式。當您水平滾動時，每個專案都會整齊地與滾動捕捉點對齊。

    <p class="text-center">With <strong>snap-x</strong>,

Tailwind CSS 強制捕捉點

此示例演示如何透過使用 **snap-mandatory** 類來使用 Tailwind CSS Scroll Snap 型別類，該類確保在您水平滾動時，專案始終對齊到最近的捕捉點，從而改善視覺對齊。

示例

<!DOCTYPE html>
<html lang="en">
<head>
    <script src="https://cdn.tailwindcss.com"></script>
</head>

<body class="p-4">
    <h2 class="text-xl font-bold mb-2">
        Tailwind CSS Scroll Snap Type
    </h2>
    <h2 class="text-xl font-bold mb-4">scroll-snap-mandatory</h2>
    <div class="flex overflow-x-auto snap-x snap-mandatory gap-4 mb-4">
        <div class="snap-center flex-shrink-0 w-96 h-32 bg-red-500 
                    text-white flex items-center justify-center">
                Block A
        </div>
        <div class="snap-center flex-shrink-0 w-96 h-32 bg-blue-500 
                    text-white flex items-center justify-center">
                Block B
        </div>
        <div class="snap-center flex-shrink-0 w-96 h-32 bg-green-500 
                    text-white flex items-center justify-center">
                Block C
        </div>
    </div>
    <p class="text-center">With <strong>snap-mandatory</strong>, 
        items will always snap to the nearest point.
    </p>
</body>

Tailwind CSS 使用捕捉臨近性進行滾動對齊

此示例演示 **snap-proximity** 類，該類確保專案在您水平滾動時捕捉到最近的點。當您接近捕捉點時，滾動會將專案對齊到該點，從而提供更流暢的滾動體驗。

示例

<!DOCTYPE html>
<html lang="en">
<head>
    <script src="https://cdn.tailwindcss.com"></script>
</head>

<body class="p-4">
    <h2 class="text-xl font-bold mb-2">
        Tailwind CSS Scroll Snap Type
    </h2>
    <h2 class="text-xl font-bold mb-4">scroll-snap-proximity</h2>
    <div class="flex overflow-x-auto snap-x snap-proximity gap-4 mb-4">
        <div class="snap-center flex-shrink-0 w-96 h-32 bg-red-500 
                    text-white flex items-center justify-center">
                Block X
        </div>
        <div class="snap-center flex-shrink-0 w-96 h-32 bg-blue-500 
                    text-white flex items-center justify-center">
                Block Y
        </div>
        <div class="snap-center flex-shrink-0 w-96 h-32 bg-green-500 
                    text-white flex items-center justify-center">
                Block Z
        </div>
    </div>
    <p class="text-center">With <strong>snap-proximity</strong>,
        items align to the nearest point when close.
    </p>

使用強制對齊進行垂直捕捉滾動

此示例演示如何使用 Tailwind CSS Scroll Snap 型別類。以下程式碼應用 **snap-y** 和 **snap-mandatory**，使垂直滾動流暢且精確。當您滾動瀏覽專案時，每個專案都將整齊地捕捉到位，確保一致且有序的檢視。
