This property can be set with other background properties by using the IHTMLRuleStyle::background composite property.

In Windows Internet Explorer 9, the background of a box can have multiple layers. The number of layers is determined by the number of comma-separated values in the IHTMLRuleStyle::backgroundImage property. Each of the images is sized, positioned, and tiled according to the corresponding value in the other background properties (IHTMLRuleStyle::backgroundAttachment, IHTMLCSSStyleDeclaration::backgroundClip, IHTMLCSSStyleDeclaration::backgroundOrigin, IHTMLRuleStyle::backgroundPosition, IHTMLRuleStyle::backgroundRepeat, and IHTMLCSSStyleDeclaration::backgroundSize). The first image in the list is the layer closest to the user, the next one is painted behind the first, and so on.

  height: 150px;
  float: left;
  margin-right: 10px;
  margin-top: 10px;
}
.circle-repeat-x {
  background-color: aqua;
  background-image: url(circle.png);
  background-repeat: repeat-x;
  background-position: 50% 50%;
}
.circle-repeat-y {
  background-color: aqua;
  background-image: url(circle.png);
  background-repeat: repeat-y;
  background-position: 50% 50%;
}
.circle-repeat {
  background-color: aqua;
  background-image: url(circle.png);
  background-repeat: repeat;
  background-position: 50% 50%;
}    
.circle-space {
  background-color: aqua;
  background-image: url(circle.png);
  background-repeat: space;
  background-position: 50% 50%;
}
