How can I fix the issue of having a small amount of background image below the fold on mobile browsers in Webflow? I have tried using custom CSS and JavaScript codes, but it did not work.
TL;DR
- Set the section to min-height: 100vh and ensure margin, padding, and overflow are set to 0/hidden.
- Configure background image settings to Cover, Center, No Repeat, and adjust mobile-specific styles as needed to accommodate viewport changes.
It sounds like you're facing an issue where small gaps or extra background image appears just below the visible fold, particularly on mobile browsers in Webflow. Here’s how to properly address this.
1. Check Section Height Settings
- Make sure the section holding the background image is set to height: 100vh (100% of the viewport height).
- In Webflow Designer, select the section, then under Style Panel, set Height to 100vh.
2. Double-Check Overflow Settings
- Set Overflow to Hidden on both the problematic section and the Body if necessary.
- This prevents scroll leaks that can reveal unexpected gaps.
3. Avoid Default Margin or Padding
- Ensure the section containing the background has Margin: 0 and Padding: 0.
- Also double-check Body, Html (All Pages), or parent containers for default browser margins that could cause slight scrolling.
4. Use Background Image Settings Properly
- Set the background image to Cover, Center Center, No Repeat.
- In the Background section of Webflow's Style Panel:
- Size: Cover
- Position: Center
- Repeat: No Repeat
- Attachment: Scroll (avoid Fixed on mobile due to performance issues).
5. Account for Mobile Browser UI
- Mobile browsers often hide/show their address bar during scroll, causing "vh" units to misbehave slightly.
- To fix viewport issues, use a min-height workaround:
- Set your section to min-height: 100vh instead of rigid height: 100vh.
- This helps when browser UI changes affecting viewport height.
6. Optional: Use Webflow's Built-In Responsive Settings
- Switch to mobile and tablet views in Webflow and inspect if the section behaves correctly.
- Adjust background image position, size, or min-height specifically for mobile views if needed.
Summary
To properly fix the mobile background image gap in Webflow:
- Set the section to min-height: 100vh.
- Ensure margin, padding, and overflow settings are reset.
- Configure the background image settings correctly (Cover, Center, No Repeat).
- Account for mobile viewport behavior without relying purely on CSS or JavaScript hacks.
Let me know if you want a more advanced technique using viewport units corrected by JavaScript—there’s a way but it's often unnecessary after doing the above!
