Remarks

For elements rendered as a single box, the background-origin property specifies the background positioning area. For elements rendered as multiple boxes (for instance, inline boxes on several lines or boxes on several pages), this property specifies which boxes determine the background positioning areas.

If the background-attachment value for an image element is "fixed", then the background-origin property has no effect. In this case, the background positioning area is the initial containing block.

The background of a box can have multiple layers. The number of layers is determined by the number of comma-separated values in the background-image property. Each of the images is sized, positioned, and tiled according to the corresponding value in the other background properties (background-attachment, background-clip, background-origin, background-position, background-repeat, and background-size). The first image in the list is the layer closest to the user, the next one is painted behind the first, and so on.
