backdrop-filter

Baseline 2024

Newly available

Since ⁨September 2024⁩, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The backdrop-filter CSS property lets you apply graphical effects such as blurring or color shifting to the area behind an element. Because it applies to everything behind the element, to see the effect the element or its background needs to be transparent or partially transparent.

Try it

backdrop-filter: blur(10px);

backdrop-filter: invert(80%);

backdrop-filter: sepia(90%);

<section class="default-example" id="default-example">
  <div class="example-container">
    <div id="example-element">Example</div>
  </div>
</section>

.example-container {
  background-image: url("/shared-assets/images/examples/balloon.jpg");
  background-size: cover;
  width: 200px;
  height: 200px;
  display: flex;
  align-items: center;
  justify-content: center;
  color: black;
}

#example-element {
  font-weight: bold;
  flex: 1;
  text-align: center;
  padding: 20px 10px;
  background-color: rgb(255 255 255 / 0.2);
}
