CSS spec: > The element is rendered following the usual rules of CSS. Replaced elements other than widgets are not affected by this and remain replaced elements. Widgets must not have their native appearance, and instead must have their primitive appearance. See § 7.2.2 Effects of appearance on Decorative Aspects of Elements and § 7.2.3 Effects of appearance on Semantic Aspects of Elements for details.
