How to Blur Background Behind Elements in CSS

How to Blur Background Behind Elements in CSS

Ferenc Almasi β€’ 2020 November 30 β€’ πŸ“– 1 min read

You can use the backdrop-filter property in CSS to blur the background image behind an element with a transparent background:

.background {
    background-image: url(castle.jpg)
}

.backdrop {
    backdrop-filter: blur(1);
}
backdrop.css

It applies to everything behind the element where the backdrop-filter is defined, therefore make sure you make the element at least partially transparent in order to see the result. This property is often used to blur out the background behind a popup.

Also, this not only works with blur, but with other filter functions as well.

.backdrop {
    backdrop-filter: brightness(50%);
    backdrop-filter: contrast(50%);
    backdrop-filter: drop-shadow(0 0 5px #000);
    backdrop-filter: grayscale(100%);
    backdrop-filter: hue-rotate(90deg);
    backdrop-filter: invert(100%);
    backdrop-filter: opacity(50%);
    backdrop-filter: sepia(100%);
    backdrop-filter: saturate(100%);
}
backdrop.css
