How to Prevent Blur Filters from Affecting Child Elements?

How to Remove Blur Effect on Child Elements

When applying a blur filter to a parent element, it can sometimes affect its child elements as well. To prevent this undesired effect, a clever solution involves creating an additional div within the parent element.

Solution:

1. Create an Overlay Div:

   Nest a div within the parent element with a background image that matches the blur effect. Assign it a lower z-index than the parent div.

   <code class="html"><div class="content">
       <div class="overlay"></div>
       <div class="opacity">...</div>
   </div></code>

2. Apply Blur Effect to Overlay Div:

   Apply the blur effect to the overlay div instead of the parent div using CSS:

   <code class="css">.content .overlay {
       background-image: url('...');
       -webkit-filter: blur(3px);
       -moz-filter: blur(3px);
       -o-filter: blur(3px);
       -ms-filter: blur(3px);
       filter: blur(3px);
       z-index: 0;
   }</code>

3. Position Opacity Div in Front:

   The opacity div should be positioned in front of the overlay div with a higher z-index.

   <code class="css">.opacity {
       z-index: 10;
   }</code>

Benefits of This Approach:

• The blur effect is contained within the overlay div, preventing it from affecting child elements.
• The opacity div can be used to control the opacity and other properties of the content without interfering with the blur effect.
