space

The image is repeated as often as will fit within the background positioning area without being clipped and then the images are spaced out to fill the area.

round

The image is repeated as often as will fit within the background positioning area. If it doesn't fit a whole number of times, it is rescaled so that it does.

no-repeat

The image is placed once and not repeated in this direction.
