How to fix the issue of a Webflow site extending beyond the bottom of the browser when using 100vh or fixed position for elements?

If your Webflow site extends beyond the bottom of the browser when using 100vh or fixed position elements, it's likely due to how Webflow and some browsers calculate viewport height. Here’s how to fix it:

1. Use 100dvh Instead of 100vh

• Some mobile browsers interpret 100vh differently, causing extra space.
• Replace 100vh with 100dvh (dynamic viewport height) in your custom CSS or Webflow settings.

2. Adjust Parent Element Overflow Settings

• Select the body or wrapper container.
• Set overflow: hidden to prevent unwanted vertical scrolling.

3. Check for Margins and Padding

• Inspect elements in Webflow’s Designer or browser DevTools.
• Remove any unwanted bottom margins or padding on elements that might push content down.

4. Avoid Fixed Position on Key Elements

• Fixed elements can cause layout shifts if improperly sized.
• Instead of position: fixed for full-screen sections, try position: sticky with top: 0.

5. Set a Custom CSS Fix in Webflow

• Go to Project Settings > Custom Code and add this inside the <style> tag:
  ```
  html, body {
  height: 100dvh;
  overflow: hidden;
  }
  ```
• This forces the correct browser behavior for height constraints.

Summary

To fix a Webflow site extending beyond the browser's bottom with 100vh or fixed elements, use 100dvh instead of 100vh, ensure no unwanted margins/padding, avoid full-page fixed elements when possible, and apply an overflow fix if needed.
