How can I add a fullwidth video or background image to a single page which is not the home page?
Please try to do the following. Go to your Dashboard → Appearance → Customize → Header area → Header type → change Site header type → click Save & Publish button.
Please feel free to ask any other questions that you might have.
Kind Regards, Roman.
Thanks, I was able to add a header video by using the customizer. Using the page body class I was bale to remove the header video from all but one page. Now, I need to add header background image to a different page. Can the Sydney customizer handle these two types of background media? One page with a background video, another with a background image?
