 - `<dashed-ident>`
-  - : Specifies the name of an existing named timeline (i.e., declared using {{cssxref("scroll-timeline-name")}} or {{cssxref("view-timeline-name")}}) defined on a descendant element. This increases the timeline scope to the current element and to any of its descendants.

Sets the scope so that the specified `scroll-timeline-name` or `view-timeline-name` values, when set in the subtree, can only be bound to by positioned elements in the same subtree.
