Remarks

Starting in Windows Internet Explorer 8, the -ms-background-position-y property is an extension to Cascading Style Sheets (CSS), and can be used as a synonym for background-position-y in IE8 Standards mode.

As of Internet Explorer for Windows Phone 8.1 Update, Internet Explorer for Windows Phone supports "-webkit-background-position-y" as an alias for this property.

Examples

The following example shows the result of different background-position-y settings for each of the three div objects. The first div object sets background-position-y to 90%. This represents a vertical offset of 90% relative to the width of the background positioning area. The second div object sets background-position-y to 20 pixels and sets the vertical offset on the x-coordinate to 20 pixels. The third div object sets background-position-y to center. This is equivalent to a vertical offset of 50%.

Three div objects demonstrate different settings for the background-position-y property.
