Code for Desktop/Mobile different landing page. Help needed.

I am trying to have 2 different landing pages for my site. One for when you login on a desktop and the other for mobile.

I would like a background video to play for the desktop viewing but the background be a still image when viewed on a mobile device. I am using 7.1. Is there a code to achieve this or any other way? Thx

I think that video backgrounds will default to using a mobile fallback image anyways, so you shouldn't have a problem with that. Just scroll to the bottom of the tool editor and upload your fallback 😄

I appreciate the response. I have tried that and it still shows the video in the background which isn't fit for the mobile screen. Any other suggestions? @Wolfsilon
