The CSS -moz-background-inline-policy Mozilla extension property specifies how the background image of an inline element is determined when the content of the inline element wraps onto multiple lines. The choice of position has significant effects on repetition.


  • bounding-box - The background image is positioned (and repeated) in the smallest rectangle that contains all of the inline boxes for the element. It is then clipped to be visible only within those boxes, according to the -moz-background-clip property.
  • continuous - The background image is positioned (and repeated) as if the inline box were not broken across lines, and then the long rectangle is sliced into pieces for each line.
  • each-box - The background image is positioned (and repeated) separately for each box of the inline element. This means that an image with background-repeat:no-repeat; may be repeated multiple times.
