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.

[1] Gecko supported from version 1.1 to version 1.9.2 (Firefox 3.6 / Thunderbird 3.1 / Fennec 1.0) a different, and prefixed, syntax: -moz-background-origin: padding | border.

In addition to the unprefixed support, Gecko 44.0 (Firefox 44.0 / Thunderbird 44.0 / SeaMonkey 2.41) added support for a -webkit prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.

[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.
