​
Basic usage

​
Changing an element's opacity

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

opacity-100

opacity-75

opacity-50

opacity-25

<button class="bg-indigo-500 opacity-100 ..."></button>
<button class="bg-indigo-500 opacity-75 ..."></button>
<button class="bg-indigo-500 opacity-50 ..."></button>
<button class="bg-indigo-500 opacity-25 ..."></button>

​
Applying conditionally

​
Hover, focus, and other states

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:opacity-100 to only apply the opacity-100 utility on hover.

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

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

​
Breakpoints and media queries

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:opacity-100 to apply the opacity-100 utility at only medium screen sizes and above.

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

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.


​
Using custom values

​
Customizing your theme

By default, Tailwind provides several opacity utilities for general purpose use. You can customize these values by editing theme.opacity or theme.extend.opacity in your tailwind.config.js file.

tailwind.config.js
module.exports = {
  theme: {
    extend: {
      opacity: {
        '67': '.67',
      }
    }
  }
}

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

​
Arbitrary values

If you need to use a one-off opacity value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="opacity-[.67]">
  <!-- ... -->
</div>

Learn more about arbitrary value support in the arbitrary values documentation.
