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. 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.
3. Since Firefox 49, also supports the -webkit prefixed version of the property.
4. In IE 7 and before, Internet explorer was behaving as if background-origin: border-box was set. In Internet Explorer 8, as if background-origin: padding-box, the regular default value, was set.
5. In IE 7 and IE 9 of Internet Explorer, it always behaved like background-clip: padding if overflow: hidden | auto | scroll.
