background-position Attribute | backgroundPosition Property
Sets or retrieves the position of the background of the element.
Syntax
HTML { background-position: sPosition } Scripting object.style.backgroundPosition [ = sPosition ]
Possible Values
sPosition String that specifies one or two of the following values:
length Floating-point number, followed by an absolute units designator (cm, mm, in, pt, pc, or px) or a relative units designator (em or ex). For more information about the supported length units, see CSS Length Units. percentage Integer, followed by a %. The value is a percentage of the width or height of the object. vAlignment Vertical alignment value consisting of one of the following:
top Vertical alignment is at the top. center Vertical alignment is centered. bottom Vertical alignment is at the bottom. hAlignment Horizontal alignment value consisting of one of the following:
left Horizontal alignment is to the left. center Horizontal alignment is centered. right Horizontal alignment is to the right. The property is read/write with a default value of 0% 0%; the cascading style sheets (CSS) attribute is not inherited.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see dynamic properties
.
Remarks
If only one value is set, that value applies to the horizontal coordinate, and the vertical is set to 50%. If both values are set, the first value applies to the horizontal coordinate and the second value applies to the vertical.
Setting the values to 0% 0% positions the background-image to the upper left corner of the element's content excluding the padding.
Specifying right center has the following effect: Because right is assumed to be an x-coordinate direction, right will overwrite the center value; the background shifts right accordingly.
This property may be set together with the other background properties using the background composite property.
Example
The following examples use the background-position attribute and the backgroundPosition property to specify the position of a background image.
This example uses a call to an embedded (global) style sheet to move the sphere.
