Background image origin
-ah-background-origin specifies the area within which the background image is positioned. The allowed values correspond to the three parts of the CSS box model: border-box, padding-box, and content-box. The default is padding-box. background-position specifies the position of the image within the box, where ‘0% 0%’ (which is also ‘0 0’) is at the top-left of the positioning area and ‘100% 100%’ is at the bottom-right of the positioning area. -ah-background-origin does not affect either clipping of the image or repetitions of the image:

In the following examples, the dotted border indicates the extent of the content box of the outer block, and the text indicates the -ah-background-clip value. All background images are the same size.

The examples use these images for repeated and non-repeated backgrounds, respectively: and

Single, non-repeated background image at '0% 0%'
'border-box'
'padding-box’'
'content-box'

Non-repeated and repeated background image at '0% 0%'
'border-box'
'padding-box'
'content-box'

Single, non-repeated background image at '100% 100%'
'border-box'
'padding-box'
'content-box'

Non-repeated and repeated background image at '100% 100%'
'border-box'
'padding-box'
'content-box'
