Opacity

Usage

Control the opacity of an element using the opacity-{amount} utilities.

Responsive

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

<div class="opacity-100 md:opacity-50 ...">
  <!-- ... -->
</div>

Customizing

Opacity Scale

By default Tailwind provides five opacity utilities based on a simple numeric scale. You change, add, or remove these by editing the theme.opacity section of your Tailwind config.

  // tailwind.config.js
  module.exports = {
    theme: {
      opacity: {
        '0': '0',
-       '25': '.25',
-       '50': '.5',
-       '75': '.75',
+       '10': '.1',
+       '20': '.2',
+       '30': '.3',
+       '40': '.4',
+       '50': '.5',
+       '60': '.6',
+       '70': '.7',
+       '80': '.8',
+       '90': '.9',
        '100': '1',
      }
    }
  }

Variants

By default, only responsive, group-hover, focus-within, hover and focus variants are generated for opacity utilities.

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

For example, this config will also generate active variants:

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       opacity: ['active'],
      }
    }
  }

Disabling

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

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