ShadowRoot

Generated from idl/dom.webidl when the site was built at 7aa23e2.

ShadowRoot is an interface in idl/dom.webidl, inheriting DocumentFragment, exposed in Window. What it does is on MDN; this page says what niso has of it.

Element.attachShadow is not supported, so there are no shadow roots; the interface is here for code that tests for one.
