Box Model

Built-in widgets and native groups use the same shared box-model keys.

Keys

• margin_x
• margin_y
• padding_x
• padding_y
• spacing

Meaning

margin_x and margin_y control outer spacing around a widget or group.

padding_x and padding_y control inner spacing inside a widget or group.

spacing controls the gap between children inside a group or layout.

Spaces widget

For the native spaces widget:

• [builtins.spaces] controls the outer container placement and shared box model.
• [builtins.spaces.layout] controls the internal workspace-pill layout.

This keeps the outer bar placement separate from the internal workspace button layout.
