Why doesn't my background video display properly in the Webflow designer with the correct height?

If your background video is not displaying with the correct height in Webflow Designer, it is likely due to styling constraints or missing settings. Follow these steps to troubleshoot and fix the issue.

1. Check the Parent Container's Height

• Ensure that the div block or section containing the background video has a defined height.
• If it's set to auto, try setting it to 100vh (viewport height) or a specific pixel value.

2. Inspect the Background Video Element

• Select the Background Video element and verify that its width and height are set correctly.
• If height is set to auto, try using 100% or a fixed value.

3. Review Flexbox or Grid Settings

• If the video is inside a flexbox or grid container, check if the parent has a conflicting align-items or justify-content setting.
• Try setting the parent div to display: block temporarily to see if it affects the height.

4. Adjust Object Fit and Position

• Go to the Style panel of the Background Video element.
• Set object-fit to cover (so the video maintains its proportions without stretching).
• Adjust object-position (e.g., center, top, or bottom) if needed.

5. Verify Video Aspect Ratio

• If the source video has a letterbox or different aspect ratio, it may not fill the container properly.
• Consider cropping the video before uploading or adjust Webflow’s resize settings.

6. Test with a Placeholder Image

• Sometimes, a missing video preview can cause display issues.
• Try adding a temporary background image to see if the layout behaves differently.

7. Publish and Test on Live Site

• The Webflow Designer view may sometimes display elements differently than the published site.
• Publish your site and check the video layout in a browser.

Summary

Check the parent height settings, adjust object-fit, and confirm the video aspect ratio. If issues persist, publish the site and test outside Webflow Designer.
