CSS :scope pseudo-class

A scope element forms a context for a block of styles. That element provides a reference point for selectors to be matched against. A scope element is defined using the scoped attribute. Styles declared with scoped attributes will be applied to all elements inside its parent element.

Syntax:

:scope
