Background-size
CSS3 gives you a way to specify the size of background images. You can specify this size in pixels, width and height, or in percentages. When you specify a size as a percentage, the size is relative to the width or height of the area that you have pointed out using background-origin.
The only browsers having this feature implemented so far are Opera 9.5, Safari 3 and Konqueror, they use -o-background-size, -webkit-background-size and -khtml-background-size.
This div has
background-size: 200px 50px. The background image should be really small, in the left upper corner of this div.
