The CSS background-position-x property is used, if a background-image is specified, to specify the initial position on the X-axis of the background image specified in the browser window if it is not continuously tiled in the element's rendering box. A minimum value for this property indicates the left side of the rendering box, and a maximum value is at the right side. The Y-axis component of the background position can be specified using the background, background-position or background-position-y properties.
