The backdrop-filter property in CSS is used to apply filter effects (grayscale, contrast, blur, etc) to the background/backdrop of an element. The backdrop-filter has the same effect as the filter property, except the filter effects are applied only to the background and instead of to the elementβs content.

Syntax:
backdrop-filter: <filter-function> [<filter-function>]* | none
<filter-function> can be any one of the following:
- blur()
- brightness()
- contrast()
- drop-shadow()
- grayscale()
- hue-rotate()
- invert()
- opacity()
- saturate()
- sepia()

You can apply multiple filter to a backdrop.
Example:
backdrop-filter: grayscale(0.5) opacity(0.8) // .... and more
Let's see an example that how we use backdrop-filter.
<div class="container">
<div class="content">
<p>
Lorem ipsum dolor sit amet, consectetur adipisicing elit.
</p>
<p>
Lorem ipsum dolor sit amet, consectetur adipisicing elit. Officiis, quae distinctio magnam, laborum iusto itaque autem! Molestiae enim distinctio molestias, dolores ea quasi magni nisi aspernatur magnam, voluptate eum fuga.
</p>
</div>
</div>
.content {
background-color: rgba(255, 255, 255, 0.5);
-webkit-backdrop-filter: blur(10px);
backdrop-filter: blur(10px);
}
