Brightness

Usage

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

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

Responsive

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

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

Customizing

Variants

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

Disabling

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

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