Grayscale

Tailwind CSS version
v2.1+

Utilities for applying grayscale filters to an element.

Default class reference

Class
Properties
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

默认情况下, 针对 grayscale 功能类,只生成 responsive 变体。

您可以通过修改您的 tailwind.config.js 文件中的 variants 部分中的 grayscale 属性来控制为 grayscale 功能生成哪些变体。

例如,这个配置将生成 hover and focus 变体:

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

Disabling

如果您不打算在您的项目中使用 grayscale 功能,您可以通过在配置文件的 corePlugins 部分将 grayscale 属性设置为 false 来完全禁用它们:

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