This solution enables you to add a fullscreen responsive WordPress hosted MP4 video to the front page 1 widget background in Altitude Pro version 1.1.3 & newer.
Note : If using version 1.4 or 1.5, this more recent tutorial adds a customizer setting to enable adding your video without hard coding the link n the front page template file.
The video covers the full screen for the front page 1 widget background until 800px width which is when the mobile menu icon is displayed and the site header is no longer transparent on screens below 800px width.
If you’re using a older version of Altitude Pro, you can use this solution.
The code modifications are included in a fresh copy of the Altitude Pro themes front-page.php & style.css files which logged in members can access below. Otherwise, you can manually install the code modifications using the instructions for logged in members below.
