I'm working on the "Una" template. I just changed my background on the hero unit of the default media type/viewport and noticed the background image on the other media types/viewports isn't changing. Isn't this supposed to happen automatically as per your tutorials?
I then took a small image and tiled it.The background images still didn't change but the tiling property cascaded down to the other media types/viewports.
How can make the background images cascade down the media viewport automatically wiyhout having to manually change them for each viewport?
