Sets the background positioning area of a box or multiple boxes.
String that specifies the position of the box or boxes.
Default. The position is relative to the padding box. For single boxes, "0 0" is the upper-left corner of the padding edge; "100% 100%" is the lower-right corner.
The position is relative to the border box.
The position is relative to the content box.
The property has a default value of padding-box. It is not inherited.
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 this image 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.
This property is defined in CSS Selectors Level 3 .
