Summary

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

If no background image or color is set, this property will only have a visual effect when the border has transparent regions or partially opaque regions (due to border-style or border-image); otherwise the border covers up the difference.

[1] Webkit also supports the prefixed version of this property, and in that case, in addition to the current keywords, the alternative synonyms are: padding, border, and content.

[2] Against a related blog post, WebKit does not include text decorations or shadows in the clipping.

[3] Gecko supported, from version 1.1 to version 1.9.2, which corresponds to Firefox 1.0 to 3.6 included, a different and prefixed syntax: -moz-background-clip: padding | border.

[4] Gecko supports the -webkit prefixed version of the property for compatibility with other browsers and to support the text value but maps it to the unprefixed version of background-clip. It is behind the layout.css.background-clip-text.enabled pref, not activated by default, in Firefox 48. Against a related blog post, Gecko does not include text decorations or shadows in the clipping.

[5] Internet Explorer 7 supported, but in other versions of Internet Explorer it behaves like background-clip:padding if overflow: hidden | auto | scroll.
