Divide Opacity

Tailwind CSS version

v1.4.0+

Utilities for controlling the opacity borders between elements.

Class reference

Usage

Control the opacity of borders between elements using the .divide-opacity-{amount} utilities.

<div class="divide-y-4 divide-black divide-opacity-25">
  <div class="text-center py-2">1</div>
  <div class="text-center py-2">2</div>
  <div class="text-center py-2">3</div>
</div>

Responsive

To control the opacity of borders between elements at a specific breakpoint, add a {screen}: prefix to any existing divide opacity utility. For example, use md:divide-opacity-50 to apply the divide-opacity-50 utility at only medium screen sizes and above.

<div class="divide-y-2 divide-blue-500 divide-opacity-75 md:divide-opacity-50">
  <!-- ... -->
</div>

Customizing

To customize the opacity values for all opacity-related utilities at once, use the opacity section of your tailwind.config.js theme configuration:

  // tailwind.config.js
  module.exports = {
    theme: {
      extend: {
        opacity: {
+         '10': '0.1',
+         '20': '0.2',
+         '95': '0.95',
        }
      }
    }
  }

If you want to customize only the divide opacity utilities, use the divideOpacity section:

  // tailwind.config.js
  module.exports = {
    theme: {
      extend: {
        divideOpacity: {
+         '10': '0.1',
+         '20': '0.2',
+         '95': '0.95',
        }
      }
    }
  }

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

Responsive and pseudo-class variants

By default, only responsive variants are generated for divide opacity utilities.

You can control which variants are generated for the divide opacity utilities by modifying the divideOpacity property in the variants section of your tailwind.config.js file.

For example, this config will also generate hover and focus variants:

  // tailwind.config.js
  module.exports = {
    variants: {
      // ...
-     divideOpacity: ['responsive'],
+     divideOpacity: ['responsive', 'hover', 'focus'],
    }
  }

Disabling

If you don’t plan to use the divide opacity utilities in your project, you can disable them entirely by setting the divideOpacity property to false in the corePlugins section of your config file:

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