Drop Shadow

Usage

Use the drop-shadow-{amount} utilities alongside the filter utility to add a drop shadow to an element.

<div class="filter drop-shadow-lg ...">
  <!-- ... -->
</div>

Responsive

To control an element’s drop shadow at a specific breakpoint, add a {screen}: prefix to any existing drop-shadow utility. For example, use md:drop-shadow-xl to apply the drop-shadow-xl utility at only medium screen sizes and above.

<div class="filter drop-shadow-md md:drop-shadow-xl ...">
  <!-- ... -->
</div>

Customizing

You can customize which drop-shadow utilities are generated using the dropShadow key in the theme section of your tailwind.config.js file.

  // tailwind.config.js
  module.exports = {
    theme: {
+     extend: {
+       dropShadow: {
+         '3xl': '0 35px 35px rgba(0, 0, 0, 0.25)',
+       }
+     }
    }
  }

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

Variants

默認情況下, 只有 響應式 的 drop-shadow 變化模式 (variants) 會產生。

在 tailwind.config.js 的 variants 區塊中變更 dropShadow 屬性來決定有哪些變化模式會生成。

舉個例子來說，這個設定將會生成 響應式 和 hover 的變化模式。

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       dropShadow: ['responsive', 'hover'],
      }
    }
  }

Disabling

如果你不打算在專案中使用 drop-shadow 功能，可以在你的設定檔裡的 corePlugins 屬性中將 dropShadow 設定為 false 來停用功能：

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     dropShadow: false,
    }
  }
