01 / THE IDEA
What does it mean?
Use size, position, contrast, and grouping to guide attention. On a busy screen, check whether the page title and main action stand out when you scan it quickly.
02 / IN PRACTICE
Make it concrete.
Illustrative example: A billing page emphasizes amount due and payment action while keeping account details secondary.
03 / WHAT TO WATCH FOR
A common mistake.
Making every title, button, and badge equally loud.
04 / WHEN IT HELPS
When should you use it?
When people cannot tell where to focus on a busy page.
