​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:object-scale-down to only apply the object-scale-down utility on hover.

<img class="object-contain hover:object-scale-down">

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:object-scale-down to apply the object-scale-down utility at only medium screen sizes and above.

<img class="object-contain md:object-scale-down">
