What could be causing the big white border when setting the overflow setting of divs to scroll in Webflow?

TL;DR
  • Use overflow: auto instead of scroll to avoid forced scrollbars creating extra space.  
  • Remove any unwanted padding or margins on the scrollable div or its parent.  
  • Ensure the scroll container has a solid background to prevent white edges from showing through.  
  • Set inner content to 100% width/height if it’s not filling the container.  
  • Check display settings like flex/grid to ensure they don’t affect overflow behavior.  
  • Test across different devices and browsers to account for scrollbar differences.

You're likely seeing a white border or padding when using overflow: scroll on a div in Webflow due to one or more of the following layout or styling issues.

1. Scrollbars Creating Extra Space  

  • Overflow: scroll always forces scrollbars, even if content doesn’t overflow.
  • Scrollbars may take up width/height, especially on Windows, creating what looks like a white edge.
  • Fix: Use overflow: auto instead of scroll so scrollbars only appear when needed.

2. Unwanted Padding or Margins  

  • The scrolling div or its parent may have unintended padding or margin applied.
  • A common mistake is adding padding on the same axis as the scroll, which adds visible space.
  • Fix: Check all relevant elements for left/right padding (for horizontal scroll) or top/bottom padding (for vertical scroll).

3. Mismatched Background Colors  

  • If the scroll container has a transparent background, but the body or parent has a white background, the border appears white.
  • Fix: Ensure the scroll container has a solid background color that matches your design.

4. Inner Content Not Filling Container  

  • If the content inside the scrollable div doesn’t fully fill its width or height, you’ll see white space around it.
  • Fix: Set inner elements to 100% width/height as needed, or use min-width / min-height if resizing is dynamic.

5. Display Settings Affecting Overflow  

  • Some layout settings like flex or grid can affect how the content resizes and overflows.
  • Fix: Carefully review the display setting and sizing behavior of both the scrollable div and its children.

6. Device Preview Differences  

  • Scrollbars behave differently across devices.
  • Macs hide scrollbars by default, whereas Windows shows them, often leading to design discrepancies.
  • Fix: Test using Webflow’s Preview Mode and also on different browsers and OSs to confirm behavior.

Summary  

White borders with overflow: scroll are usually caused by scrollbars creating spacepadding/margin misalignment, or background color mismatches. Switch to overflow: auto, remove extra spacing, and set a matching background to fix the issue confidently.
