Examples

Basic example

Use utilities likebackdrop-opacity-50 andbackdrop-opacity-75 to control the opacity of all the backdrop filters applied to an element:

backdrop-opacity-10

backdrop-opacity-60

backdrop-opacity-95

<div class="bg-[url(/img/mountains.jpg)]">  <div class="bg-white/30 backdrop-invertbackdrop-opacity-10 ..."></div></div><div class="bg-[url(/img/mountains.jpg)]">  <div class="bg-white/30 backdrop-invertbackdrop-opacity-60 ..."></div></div><div class="bg-[url(/img/mountains.jpg)]">  <div class="bg-white/30 backdrop-invertbackdrop-opacity-95 ..."></div></div>

Using a custom value

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

<div class="backdrop-opacity-[.15] ...">  <!-- ... --></div>

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

<div class="backdrop-opacity-(--my-backdrop-filter-opacity) ...">  <!-- ... --></div>

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

Responsive design

Prefix abackdrop-filter: opacity() utility with a breakpoint variant likemd: to only apply the utility at medium screen sizes and above:

<div class="backdrop-opacity-100md:backdrop-opacity-60 ...">  <!-- ... --></div>
