To create a background blur effect in a div block on your hero section in Webflow, you'll use backdrop filters to blur the background behind the overlay. This enhances legibility without obscuring the background entirely.
1. Add a Hero Section with a Background Image
- Drag a Section into your Webflow canvas and name it something like Hero Section.
- Set a Background Image on the Hero Section using the Backgrounds panel.
- Adjust background settings: Cover, No Repeat, and Center for optimal scaling.
2. Insert the Overlay Div Block
- Add a Div Block inside your Hero Section. It will contain the content (e.g., thin text).
- Position it over the background:
- Set Position: Absolute or Relative depending on layout needs.
- Use 100% width/height if it’s meant to cover the entire section.
- Apply a semi-transparent background color, such as
rgba(255, 255, 255, 0.3), to help the blur show through.
3. Apply the Background Blur Effect
- With the overlay Div selected, go to the Effects panel.
- Under Backdrop Filter, click + Add and choose Blur.
- Set the blur strength (e.g., 10px) to your desired level of visibility and softness.
Important: The browser must support backdrop filters. They are well-supported in modern browsers but may not render correctly in older versions.
4. Style for Legibility
- Add your text elements (e.g., Heading, Paragraph) inside the overlay Div.
- Use strong contrast colors (e.g., black or dark gray) to ensure readability against a light-blurred background.
- Increase font weight if using thin typefaces, or add text shadows for additional clarity.
5. Optional: Add Border or Inner Shadows
- Boost clarity and separation from the background by applying:
- A subtle border around the overlay div.
- Or a light inner shadow to define edges.
Summary
To blur the background behind text on a hero image in Webflow, use a semi-transparent Div block with a Backdrop Filter (Blur) applied. Place your text inside this div for improved legibility, especially when using thin fonts.
