​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:align-top to only apply the align-top utility on hover.

<p class="align-middle hover:align-top">
  <!-- ... -->
</p>

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:align-top to apply the align-top utility at only medium screen sizes and above.

<p class="align-middle md:align-top">
  <!-- ... -->
</p>

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

​使用自定义值

¥Using custom values

​任意值

¥Arbitrary values

If you need to use a one-off vertical-align value that isn't included in Tailwind by default, use square brackets to generate a property on the fly using any arbitrary value.

<div class="align-[4px]">
  <!-- ... -->
</div>

Learn more about arbitrary value support in the arbitrary values documentation.
