Can I change the section background opacity in Webflow without affecting the opacity of other elements within the section?

Yes, you can change the background opacity of a section in Webflow without affecting the opacity of its child elements. Follow the steps below to achieve this effect.

1. Use a Semi-Transparent Background Color

• Select the section you want to modify.
• In the Style panel, go to the Background settings.
• Click the color swatch and adjust the opacity within the RGBA color format.
• Example: A black background with 50% opacity would be rgba(0, 0, 0, 0.5).
• This method ensures the background is transparent while keeping other elements fully visible.

2. Apply a Transparent Background Image

• Instead of a solid color, use a PNG image with transparency.
• Go to the Background settings and upload a semi-transparent image.
• Adjust size, position, and repeat properties as needed.

3. Use a Pseudo-Element (Advanced)

• If Webflow's built-in options don’t meet your needs, use a pseudo-element workaround:
• Add a div inside the section and position it absolutely with width: 100% and height: 100%.
• Apply a semi-transparent background color to this div instead of the section.
• Set z-index so it sits behind the content but remains visible.

Summary

To make only the background semi-transparent:

• Use an RGBA background color.
• Upload a transparent PNG image.
• Create a pseudo-element with absolute positioning.

These methods ensure that only the background fades, while content inside the section remains fully visible.
