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 ]

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.

Sample Code
<STYLE>
    .style1 { background-position:top center }
    .style2 { background-position:bottom right }
</STYLE>
</HEAD>
<BODY onload="oSpan.className='style1'">
<SPAN STYLE="font-size:14; width:250;" ID="oSpan"
    onmouseover="this.className='style2'" onmouseout="this.className='style1'">
. . . </SPAN>
