盒阴影

​基本用法

¥Basic usage

​添加外部阴影

¥Adding an outer shadow

使用 shadow-sm、shadow、shadow-md、shadow-lg、shadow-xl 或 shadow-2xl 工具将不同大小的外框阴影应用于元素。

¥Use the shadow-sm, shadow, shadow-md, shadow-lg, shadow-xl, or shadow-2xl utilities to apply different sized outer box shadows to an element.

<div class="shadow-md ..."></div>
<div class="shadow-lg ..."></div>
<div class="shadow-xl ..."></div>
<div class="shadow-2xl ..."></div>

​添加内阴影

¥Adding an inner shadow

使用 shadow-inner 工具将微妙的内嵌框阴影应用于元素。这对于表单控件或井之类的东西很有用。

¥Use the shadow-inner utility to apply a subtle inset box shadow to an element. This can be useful for things like form controls or wells.

<div class="shadow-inner ..."></div>

​去除阴影

¥Removing the shadow

使用 shadow-none 从元素中删除现有的框阴影。这最常用于删除在较小断点处应用的阴影。

¥Use shadow-none to remove an existing box shadow from an element. This is most commonly used to remove a shadow that was applied at a smaller breakpoint.

<div class="shadow-none ..."></div>

​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:shadow-lg to only apply the shadow-lg utility on hover.

<div class="shadow hover:shadow-lg">
  <!-- ... -->
</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:shadow-lg to apply the shadow-lg utility at only medium screen sizes and above.

<div class="shadow md:shadow-lg">
  <!-- ... -->
</div>

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

​自定义主题

¥Customizing your theme

默认情况下，Tailwind 提供了六个投影工具、一个内部阴影工具和一个用于删除现有阴影的工具。你可以通过编辑 tailwind.config.js 文件中的 theme.boxShadow 或 theme.extend.boxShadow 来自定义这些值。

¥By default, Tailwind provides six drop shadow utilities, one inner shadow utility, and a utility for removing existing shadows. You can customize these values by editing theme.boxShadow or theme.extend.boxShadow in your tailwind.config.js file.

如果提供了 DEFAULT 影子，它将用于无后缀的 shadow 工具。任何其他密钥都将用作后缀，例如密钥 '2' 将创建相应的 shadow-2 工具。

¥If a DEFAULT shadow is provided, it will be used for the non-suffixed shadow utility. Any other keys will be used as suffixes, for example the key '2' will create a corresponding shadow-2 utility.

module.exports = {
  theme: {
    extend: {
      boxShadow: {
        '3xl': '0 35px 60px -15px rgba(0, 0, 0, 0.3)',
      }
    }
  }
}

¥Learn more about customizing the default theme in the theme customization documentation.

​任意值

¥Arbitrary values

If you need to use a one-off box-shadow value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="shadow-[0_35px_60px_-15px_rgba(0,0,0,0.3)]">
  <!-- ... -->
</div>

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