opacity

Examples

Basic example

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

<!-- [!code classes: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

Prefix an opacity utility with a variant like disabled:* to only apply the utility in that state:

<!-- [!code classes:disabled:opacity-75] -->
<input class="opacity-100 disabled:opacity-75 ..." type="text" />

Learn more about using variants in the variants documentation.

Using a custom value

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

<!-- [!code classes:opacity-[.67]] -->
<button class="opacity-[.67] ...">
  <!-- ... -->
</button>

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

<!-- [!code classes:opacity-(--my-opacity)] -->
<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:

<!-- [!code classes:md:opacity-100] -->
<button class="opacity-50 md:opacity-100 ...">
  <!-- ... -->
</button>
