How to Prevent Child Elements from Inheriting Blur Effects in CSS?

Removing Blur Effect on Child Elements with CSS

When using CSS blur effects on a parent element, it's common to encounter the issue of child elements also inheriting the blur. To resolve this, we can create a separate div within the parent and apply the blur effect to it instead.

Implementation

1. Add an additional div within the content div and assign it a class, such as overlay.

<code class="html"><div class="content">
  <div class="overlay"></div>
  <div class="opacity">
    <!-- Child elements... -->
  </div>
</div></code>

2. In CSS, assign the blur effect and background image to the overlay div, ensuring that its z-index is lower than the opacity div:

<code class="css">.content {
  float: left;
  width: 100%;
}

.content .overlay {
  background-image: url('images/zwemmen.png');
  height: 501px;
  -webkit-filter: blur(3px);
  -moz-filter: blur(3px);
  -o-filter: blur(3px);
  -ms-filter: blur(3px);
  filter: blur(3px);
  z-index: 0;
}

.opacity {
  background-color: rgba(5, 98, 127, 0.9);
  height: 100%;
  overflow: hidden;
  position: relative;
  z-index: 10;
}</code>

By giving the overlay div a lower z-index, the child elements within the opacity div will be positioned above it, ensuring that they are not affected by the blur effect.
