Z-index

Overview

The z-index determines the stacking order of elements, dictating which elements appear in front of or behind others when they overlap. Elements with higher z-index values are displayed on top of those with lower values. Different UI components can share the same elevation style, such as shadows or visual depth cues, to maintain a consistent look and feel. However, each UI component should be assigned a different z-index value to accurately represent their relative stacking order within the interface.
