01 / THE IDEA
What does it mean?
A visible focus indicator shows where keyboard focus is. It helps someone see which control they have reached before they activate it or move on.
02 / IN PRACTICE
Make it concrete.
Illustrative example: A filter chip has a strong outline when tabbed to, without relying on hover styling.
03 / WHAT TO WATCH FOR
A common mistake.
Removing focus outlines simply because they look untidy.
04 / WHEN IT HELPS
When should you use it?
When making custom buttons, links, tabs, or component libraries.
