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.


Value Description
<percentage> Percentage is in reference to the dimensions of the box of the current element. Value specifies the percentage on both the image and the canvas and may be negative (20% indicates the reference point 20% from the left side of the image is to be located at 20% from the left side of the element's rendering box).
<length> Represents an absolute X-coordinate position for the image and may be negative. Examples are cm, pt, px, etc.
left Image is positioned to the left of the screen on the X-axis.
center Image is centered in the screen on the X-axis.
