How to Blur Background Images Without Affecting Content Clarity?

Blurring Background Images without Affecting Content

In an attempt to create a visually appealing design, developers often encounter a challenge when blurring the background image of a web page. However, blurring the image often affects the main content (text and elements) as well. This poses the question: how can we blur the background image without sacrificing the clarity of our content?

The solution lies in utilizing CSS and JavaScript to create a separate layer for the blurred background while keeping the content layer distinct. Here's the complete code snippet:

.blur-bgimage {
    overflow: hidden;
    margin: 0;
    text-align: left;
}
.blur-bgimage:before {
    content: "";
    position: absolute;
    width : 100%;
    height: 100%;
    background: inherit;
    z-index: -1;

    filter        : blur(10px);
    -moz-filter   : blur(10px);
    -webkit-filter: blur(10px);
    -o-filter     : blur(10px);

    transition        : all 2s linear;
    -moz-transition   : all 2s linear;
    -webkit-transition: all 2s linear;
    -o-transition     : all 2s linear;
}

This code snippet creates a pseudo-element (:before) that inherits the background image. By positioning this pseudo-element absolutely, we create a separate layer for the blurred background. The blur effect is applied using the filter property.

To blur the background, simply add the "blur-bgimage" class to the desired element. To remove the blur, remove the class. JavaScript can be used to dynamically add and remove the class, allowing for dynamic control of the blur effect.

By implementing this technique, you can create visually stunning designs with blurred background images while maintaining the clarity of your website's content.
