Dynamic HTML: The Definitive Reference

Name

backgroundPositionX, backgroundPositionY — NN n/a IE 4 DOM n/a

Synopsis

Read/Write

Top and left locations of the background image relative to the element’s content region (plus padding). These properties are not properly connected in Internet Explorer 4 for the Macintosh.

Example

document.all.div3.style.backgroundPositionX = "20"
document.all.table2.style.backgroundPositionY = "10"

Value

You should be able to specify percentage values, which are the percentage of the block-level element’s box width and height (respectively) at which point the image (or repeated images) begins. Setting percentage values, however, does not always work in IE 4 for Windows (and it doesn’t work at all on the Mac), even though they are returned as the default value units. You are safest with pixel values. None of the allowed constants except top and left are recognized.
