Web/API/HTMLStyleElement/scoped

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.

ObsoleteThis feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The HTMLStyleElement.scoped property is a Boolean value indicating if the element applies to the whole document (false) or only to the parent's sub-tree (true).

By default it contains the value of the scoped content attribute.

Syntax

value = style.scoped;
style.scoped = true;
