How can I adjust the height of my homepage video on the Dawn theme?

Topic summary

A user seeks to reduce the height of a video displayed on their homepage using the Dawn theme, finding it currently too tall.

Proposed Solutions:

  • CSS approach (GemPages): Add custom CSS to the base.css file setting max-height: 800px for the .shopify-section video selector to constrain video dimensions.

  • Video format recommendation (PageFly-Victor): The current 9:16 (vertical) video format causes cropping issues when height is reduced. Suggests converting the video to 16:9 (horizontal) aspect ratio for proper display at smaller heights, with a video conversion tool provided.

Status: The discussion remains open with two different technical approaches offered—one focusing on CSS constraints and another addressing the root cause through video reformatting. No confirmation yet on which solution the user implemented or whether either resolved the issue.

Hi [email removed]Lextensions88,

This is Victor from PageFly - Landing Page Builder App

Because your video is formatted 9:16 so when you resize the height or min-height for it the video will crop and not be good. you can try to change the video format to 19:6 to show it correctly. You can try to use my video convert
