How can I achieve a background blur effect in a div block on my hero element using Webflow? I want to ensure that thin text remains legible while overlaying a background hero image.
TL;DR
- Add a div block with backdrop blur and semi-transparent background between the hero image and text.
- Use proper positioning, Z-index layering, and Flex/Grid layout to ensure the text stays legible and centered across all devices.
To improve legibility of thin text over a hero image, you can use a background blur effect on a div block in Webflow. This creates a frosted-glass look without obscuring the hero image itself.
1. Add a Div Block for the Blur Layer
- Drag a Div Block into your hero section.
- Place it above the background image and behind your text content, or wrap your text content inside this div.
- Give it a custom name like “Blur Overlay” for organization.
2. Style the Blur Div Block
- Set Position to Absolute or Relative depending on your layout (e.g., use Absolute: Full to cover the entire hero).
- Set Background Color (e.g., white or black) with some opacity, such as rgba(255, 255, 255, 0.2) or rgba(0, 0, 0, 0.3) depending on desired contrast.
- Apply Blur using Backdrops:
- Go to the Effects section in the Style panel.
- Under Backdrop Filter, enable and set a blur value (e.g., Blur: 10px).
3. Ensure Proper Z-Index & Layering
- Set the Hero Section's background image on a separate layer or directly on the section.
- Place the Blur Overlay behind your text and above the background by setting Z-index values:
- Hero background: base level.
- Blur overlay: higher than background (e.g., Z-index: 1).
- Text content: above the blur (e.g., Z-index: 2).
4. Use Flexbox or Grid for Layout
- If your blur div is wrapping text, apply Flex or Grid to center the text vertically and horizontally on top.
- Alternatively, position text independently over the blur block with another absolute div.
5. Preview and Adjust Responsively
- Test the effect on different viewports in Webflow designer to ensure legibility.
- Adjust the blur strength and overlay color opacity as needed for contrast with background image.
Summary
Add a div block with backdrop blur between your hero image and text content, set appropriate background opacity, and use Z-index layering and layout controls to maintain legibility across devices.
