Examples

Basic example

Use opacity-<number> utilities like opacity-25 and opacity-100 to set the opacity of an element:

<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

Use the disabled: prefix to conditionally apply an opacity on disabled elements:

<input type="text" class="opacity-100 disabled:opacity-75" />

Using a custom value

Use the opacity-[<value>] syntax to set the opacity based on a completely custom value:

<button class="opacity-[.67]">
  Custom
</button>

For CSS variables, you can also use the opacity-(<custom-property>) syntax:

<button class="opacity-(--my-opacity)">
  <!-- ... -->
</button>

This is just a shorthand for opacity-[var(<custom-property>)] that adds the var() function for you automatically.

Responsive design

Prefix an opacity utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

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