要使滚动对齐起作用，你还需要在元素内的子项上设置 滚动捕捉对齐。

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 hover:snap-x to only apply the snap-x utility on hover.

<div class="hover:snap-x">
  <!-- ... -->
</div>

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:snap-x to apply the snap-x utility at only medium screen sizes and above.

<div class="md:snap-x">
  <!-- ... -->
</div>

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