Page Background Behind the Web Content?

I would like to simply add a background image to be visible if the web page is stretched wider than the content containers. How is this done?

Hi Jeff,

Not sure I understand exactly what you’re after. But if you want to make a Background image cover the whole section you can do that through the image settings when you apply that background image. (See settings on right of image)

You just need to set the image to cover
