For each page panel admins have the ability to set either a background colour or background image/video to this panel for their website.
These options can be found against any page panel in the SECTIONS part of the backend.
Below provides an example what what both look like when assigned on a website
Multiple colours cannot be selected for one page panel, only one solid colour.
When adding a background image, this can be a solid image, youtube video, vimeo video or a dailmotion video.
Maximum upload file size: 50 MB. 500 x 800 pixels is recommended. Make sure the image is cropped to suit what parts of the image/video you wish to have displayed.
