Enum StyleSpatialNavigationContain 

#[repr(C)]
pub enum StyleSpatialNavigationContain {
    Auto = 0,
    Contain = 1,
}

spatial-navigation-contain - whether this element is a spatial navigation container.

.sidebar { spatial-navigation-contain: contain; }

Under auto, only scroll containers (and the viewport) are containers, which is the spec’s default. contain adds one for an element that does not scroll - a toolbar, a dialog, a sidebar - so that arrow keys resolve among its descendants first and only leave it when nothing inside answers.

NOT INHERITED, and for a sharper reason than the action property: it marks ONE element as a boundary. Inheriting it would make every descendant a boundary too, which is the same as having none - each nested container would trap navigation one level deeper until an arrow could not move at all.

Variants

Auto = 0

A container only if this element is a scroll container.

Contain = 1

A container regardless of whether it scrolls.
