Achieving iOS 7's Blurred Overlay Effect with CSS

Apple's iOS 7 introduced a distinct blurred overlay effect that extends beyond mere transparency. Developers often wonder how to replicate this appealing visual enhancement using web technologies.

CSS Solution

CSS 3 offers a straightforward method to achieve this effect:

<code class="css">#myDiv {
    -webkit-filter: blur(20px);
    -moz-filter: blur(20px);
    -o-filter: blur(20px);
    -ms-filter: blur(20px);
    filter: blur(20px);
    opacity: 0.4;
}</code>

By adding this CSS code to an element, you can apply the blurred overlay effect. The 'blur()' filter sets the amount of blur applied, while 'opacity' controls the transparency of the element.
