The very concept of "background painting > area" *is* that definition. It can not exist regardless of > background-clip. The concept of "background painting area" did not exist in CSS 2.1. Nevertheless, it was defined in CSS 2.1 via reading �8.1 and �14.2 of that spec. CSS 2.1 did not have a background-clip property. CSS 2.1 more or less explicitly defined where the painting started and ended in terms of areas. In 3 precise spots of CSS 2.1, the areas being painted (and the one not painted) by background (color and image) were identified, without any recourse to a background-clip property and without a formal definition of the concept of "background painting area". > You can talk about the initial value of background-clip > as "the default", but it’s really paraphrasing what’s already defined. Where exactly do you see "background-clip" in the following image or flash object?
