Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Deprecated
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Draft
This page is not complete.

Use Element.createShadowRoot to create an instance of shadow DOM. When shadow DOM is created, it is always attached to an existing element. After the shadow DOM is created, the element that it is attached to is called the shadow root.

This method has been deprecated in favor of attachShadow().

Syntax

var shadowroot = element.createShadowRoot();

Parameters

No parameters.

Result value

Returns a ShadowRoot.

Specifications

This feature is no longer defined by any specifications.
