Grayscale

Tailwind CSS version
v2.1+

Utilities for applying grayscale filters to an element.

Default class reference

Class
屬性
grayscale-0--tw-grayscale: grayscale(0);
grayscale--tw-grayscale: grayscale(1);

Usage

Use the grayscale and grayscale-0 utilities alongside the filter utility to whether an element should be rendered as grayscale or in full color.

<div class="filter grayscale ...">
  <!-- ... -->
</div>

Responsive

To control an element’s grayscale filter at a specific breakpoint, add a {screen}: prefix to any existing grayscale utility. For example, use md:grayscale-0 to apply the grayscale-0 utility at only medium screen sizes and above.

<div class="filter grayscale md:grayscale-0 ...">
  <!-- ... -->
</div>

Customizing

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

  // tailwind.config.js
  module.exports = {
    theme: {
+     extend: {
+       grayscale: {
+         50: '50%',
+       }
+     }
    }
  }

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

Variants

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

tailwind.config.jsvariants 區塊中變更 grayscale 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: {
        // ...
+       grayscale: ['responsive', 'hover'],
      }
    }
  }

Disabling

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

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