How can I ensure the blur effect in Webflow covers the entire div when using CSS styles like the one shown below?
TL;DR
- Use
backdrop-filter: blur(Xpx);with a transparent background and absolute positioning to blur the background. - Set width and height to
100%and ensure the div fully covers the target area. - Apply
filter: blur(Xpx);to blur elements inside the div instead of the background. - Adjust z-index and positioning so the blurred div is correctly layered.
- Ensure browser compatibility by adding
-webkit-backdrop-filterfor Safari.
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: absoluteorfixedto 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: absolutewithtop: 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
relativepositioning.
5. Test Browser Compatibility
backdrop-filterhas limited support in older browsers. Add-webkit-backdrop-filterfor 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.
