Backdrop Grayscale

Usage

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

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

Responsive

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

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

Customizing

Variants

默认情况下， 针对 backdrop 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 backdropGrayscale 属性来控制为 backdrop grayscale 功能生成哪些变体。

例如，这个配置也将生成 hover and focus 变体:

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

Disabling

如果您不打算在您的项目中使用 backdrop grayscale 功能，您可以通过在配置文件的 corePlugins 部分将 backdropGrayscale property to false in the corePlugins section of your config file:

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