background-clip
CSS background-clip Property
CSS background-clip property specifies how far the background-color and background-image should be from the element. If the element has no background-image or background-color, this property will only have a visual effect when the border has transparent regions or partially opaque regions, otherwise, the border shows the difference.
The background-clip property is one of the CSS3 properties.
For clipping a background to a text there is also a vendor-prefixed version of the background-clip property.
