    Summary

    The background-position-x CSS property sets the initial horizontal position, relative to the background position layer defined by background-origin for each defined background image. For more information, see the background-position property, which has been widely supported.

    Note: The value of this property is overridden by any declaration of the background or background-position shorthand properties applied to the element after the background-position-x CSS property.
