Backdrop Contrast

Usage

Use the backdrop-contrast-{amount?} utilities alongside the backdrop-filter utility to control an element's backdrop contrast.

<div class="backdrop-filter backdrop-contrast-125 ...">
  <!-- ... -->
</div>

Responsive

To control an element's backdrop contrast at a specific breakpoint, add a {screen}: prefix to any existing backdrop contrast utility. For example, use md:backdrop-contrast-150 to apply the backdrop-contrast-150 utility at only medium screen sizes and above.

<div class="backdrop-filter backdrop-contrast-110 md:backdrop-contrast-150 ...">
  <!-- ... -->
</div>

Customizing

Variants

默认情况下， 针对 backdrop contrast 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 backdropContrast 属性来控制为 backdrop contrast 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: {
        // ...
+       backdropContrast: ['hover', 'focus'],
      }
    }
  }

Disabling

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

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