Mobile Priority Stack Layout

Mobile is not a smaller desktop; content and actions should restack by task priority.

Design Principle

Small screens need important information, controls, and feedback early without overlap.

Principle

Small screens need important information, controls, and feedback early without overlap.

Design action

On mobile show title, search/status, and main content first, then filters and sidebars; tables become horizontal scroll or card rows.

Examples

Positive example: Knowledge lists, detail pages, forms, and review queues. Counterexample: Sidebars squeeze the main content.

Apply when

Knowledge lists, detail pages, forms, and review queues. Desktop uses sidebars or multi-column layout.
