Why do all my Webflow site pages have a horizontal overlay, even after trying to hide overflowing content and using elements with 100vh?

Your Webflow site pages might have a horizontal overlay due to unintended overflow from certain elements. Let's explore steps to resolve this issue.

​

1. Check for Overflowing Elements

• Inspect your elements to see if any are exceeding the viewport width.
• Look for set widths on elements that extend beyond 100% or have a minimum width that exceeds the viewport.

​

2. Use overflow: hidden on Larger Containers

• Apply overflow: hidden to sections or main containers that might be allowing content to spill out.
• Avoid using it on entire pages; it should only be applied where necessary to prevent cutting off content unintentionally.

​

3. Review the Use of 100vw and 100vh

• Ensure elements using 100vw or 100vh do not have additional margins or paddings that extend them beyond the viewport.
• Consider using 100% width instead if issues persist with 100vw.

​

4. Check for Negative Margins

• Inspect elements to see if negative margins are extending elements outside the main view.
• Adjust margins that don't rely on negative values, especially on block-level elements.

​

5. Test in Webflow Designer

• Use Webflow’s Designer tools to simulate various screen sizes and check for overlay issues.
• Look at the Navigator panel to ensure elements aren’t misaligned.

​

Summary

To resolve the horizontal overlay on your Webflow site, inspect for and address any overflowing elements, consider adjustments in 100vw usage, and ensure no negative margins are involved. Use overflow: hidden strategically to manage content overflow where necessary.
