How can I ensure the blur effect in Webflow covers the entire div when using CSS styles like the one shown below?

To ensure the blur effect fully covers a div in Webflow, you need to apply the correct CSS properties. Here’s how:

1. Use backdrop-filter for Background Blur

• Apply backdrop-filter: blur(Xpx); to blur everything behind the div.
• Use position: absolute or fixed to ensure the blur persists across the page.
• Ensure the div has a transparent background (e.g., rgba(255, 255, 255, 0.5)).

2. Expand the Div to Cover the Entire Area

• Set width and height to 100% (or specific dimensions as needed).
• Use position: absolute with top: 0; left: 0; right: 0; bottom: 0; to make it fill the parent container.

3. Apply filter: blur(Xpx); for Foreground Elements

• If you want to blur elements inside the div, use filter: blur(Xpx); instead.
• This works on specific elements rather than the background.

4. Check Z-Index and Positioning

• Ensure the blurred div has a lower z-index than elements in front of it.
• If needed, wrap content in another div and apply relative positioning.

5. Test Browser Compatibility

• backdrop-filter has limited support in older browsers. Add -webkit-backdrop-filter for Safari compatibility.

Summary

Make the div cover the entire area using absolute positioning, ensure it has a transparent background, and use backdrop-filter for blurring the background or filter for blurring inside content.
