background-origin

Summary

The background-origin CSS property determines the background positioning area, that is the position of the origin of an image specified using the background-image CSS property.

Note that background-origin is ignored when background-attachment is fixed.

If the value of this property is not set in a background shorthand property that is applied to the element after the background-origin CSS property, the value of this property is then reset to its initial value by the shorthand property.

Syntax

Formal syntax: <box>#
background-origin: border-box
background-origin: padding-box
background-origin: content-box

background-origin: inherit

Values

border-box
The background extends to the outside edge of the border (but underneath the border in z-ordering).
padding-box
No background is drawn below the border (background extends to the outside edge of the padding).
content-box
The background is painted within (clipped to) the content box.

Examples

 .example {
   border: 10px double;
   padding: 10px;
   background: url('image.jpg');
   background-position: center left;
   /* The background will be inside the padding */ 
   background-origin: content-box;
}

div {
  background-image: url('logo.jpg'), url('mainback.png');
  background-position: top right, 0px 0px;
  background-origin: content-box, padding-box;
}

[2] Internet Explorer up to version 7 behaves as if there was a background-origin: border-box; Internet Explorer 8 behaves as if it were background-origin: padding-box; which is the regular default value.

[3] Webkit also supports the prefixed version of this proprietary, and in that case, in addition to the current keywords, the alternative synonyms: padding, border, and content.

[4] Konqueror 3.5.4 supports -khtml-background-origin.
