Creating a blur effect in various browsers

If you have been trying to create a blur effect for your website, you might have encountered issues where each browser demonstrates different behavior in controlling this feature. In instances where this effect can provide your website design with a particular charm, using it may present challenges.

In fact, to achieve a similar effect across all browsers, you need to use several CSS properties in a combined manner. These properties may need to be specifically named for each browser, or they can be generally used but may not provide backward compatibility.

For example, the backdrop-filter property is one of the common methods to implement this effect; however, it is essential to note that not all browsers will support this feature directly, and you should use polyfills to resolve this issue.

Another method involves using a transparent layer with a white color and applying a blur to it. This method can simplify the task and simultaneously achieve the desired blur effect.

The following is a code snippet for implementing this effect on your own projects.

Example Code Snippet

<style>
  .blur-background {
    position: relative;
    backdrop-filter: blur(10px);
    -webkit-backdrop-filter: blur(10px);
  }
  .overlay {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: rgba(255, 255, 255, 0.3);
    z-index: 1;
  }
</style>

<div class="blur-background">
  <div class="overlay"></div>
  <!-- Background content -->
</div>
