Elevation roles

Consumers choose a semantic role instead of a numeric shadow index. Borders remain required on transient surfaces for forced-colors resilience.

none

Flat or outlined surface; dense cards, panels and table shells.

elevation.none

raised

Soft local lift for hover or selection; not a blanket card state.

elevation.raised

floating

Anchored contextual surfaces, menus, popovers and inline editors.

elevation.floating

overlay

Higher transient surfaces above the working context.

elevation.overlay

modal

Blocking temporary surfaces and high-consequence confirmations.

elevation.modal

overflow

Reserved

Reserved for sticky-edge and scroll-shadow consumers.
