The background-clip CSS property specifies if an element's background, whether a <color> or an <image>, extends underneath its border.

/* Keyword values */
background-clip: border-box;
background-clip: padding-box;
background-clip: content-box;
background-clip: text;

/* Global values */
background-clip: inherit;
background-clip: initial;
background-clip: unset;

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 (due to border-style or border-image); otherwise, the border masks 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. Firefox supported, from version 1 to 3.6 included, a different and prefixed syntax: -moz-background-clip: padding | border.

3. In IE 7 and IE 8 of Internet Explorer, this property always behaved like background-clip: padding when overflow was hidden, auto, or scroll.

4. In IE 7 and IE 9 of Internet Explorer, it always behaved like background-clip: padding if overflow: hidden | auto | scroll

5. Support the prefixed version of the property only; according to the official blog, WebKit does not include text decorations or shadows in the clipping.

6. In Firefox 48, it was not activated by default and its support could be activated by setting layout.css.background-clip-text.enabled pref to true.
