Principles
1. The tab is a plane
Its placement organizes and motivates the layout of a communication.
The tab is a plane, anchored to the center (marketing) or the top left (signed-out web and product) of a layout.
2. Planes are the foundation of composition
Planes create visual distinction among groupings of content. We use planes as the foundation for a layout to ensure hierarchy, recognition, and cohesion across platforms and devices.

3. Planes are dynamic
Planes react, reveal, and conceal—adapting to the needs of the user, context, and content. They always present the best arrangement for a communication goal.
