Contrast

Tailwind CSS version
v2.1+

Utilities for applying contrast filters to an element.

Default class reference

Class
屬性
contrast-0--tw-contrast: contrast(0);
contrast-50--tw-contrast: contrast(.5);
contrast-75--tw-contrast: contrast(.75);
contrast-100--tw-contrast: contrast(1);
contrast-125--tw-contrast: contrast(1.25);
contrast-150--tw-contrast: contrast(1.5);
contrast-200--tw-contrast: contrast(2);

Usage

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

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

Responsive

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

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

For more information about Tailwind’s responsive design features, check out the Responsive Design documentation.

Customizing

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

  // tailwind.config.js
  module.exports = {
    theme: {
+     extend: {
+       contrast: {
+         25: '.25',
+       }
+     }
    }
  }

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

Variants

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

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

Disabling

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

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