background-clip property - CSS Reference

background-clip property CSS Reference

Definition and Usage

The background-clip CSS property specifies whether an element's background, either the color or image, extends underneath its border.

If there is no background image, this property has only visual effect when the border has transparent regions (because of border-style) or partially opaque regions; otherwise the border covers up the difference.

padding-box: No background is drawn below the border (background extends to the outside edge of the padding).
content-box: The background is painted within (clipped to) the content box.
