条件应用

悬停、聚焦和其他状态

Tailwind 允许您使用变体修饰符有条件地在不同状态下应用实用程序类。例如，使用 hover:snap-start 来仅 在 hover应用 snap-start.

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

详细了解, 请参考 Hover, Focus, & Other States 文档.

断点和媒体查询

您还可以使用变体修饰符来定位媒体查询，例如响应式断点、暗模式、首选减少运动等。例如, 使用 md:snap-start 来应用 snap-start 程序，适用于中等屏幕尺寸及以上。

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

进一步了解，请参考 响应式设计, 暗黑模式 和 媒体查询.
