You might want to set a video background type for your pages header.
However, the video background type might not be displayed on mobile devices.
This happens because, on mobile and tablet, this feature is disabled by default. Video backgrounds affect the website performance on mobile devices, because of the amount of data that is being processed.
For such cases, Highlight offers an alternative solution: video posters.
While video background files are loading or do not play on mobile devices, an alternative image (video poster) is shown to the users.
