What it is
Primary is a visual priority, not a different browser element. Strong contrast helps people find the next step while the rest of the action group remains less prominent.
When to use it
Give the current task one clear primary action, such as creating the project.
Know the difference
Primary does not mean destructive; destructive actions need a separate warning treatment.
Across platforms
Web
Use a native button for an action and an anchor for navigation. Preserve keyboard activation and a visible focus indicator.
iOS · iPadOS · Android
Provide a comfortable touch target, use familiar system symbols when appropriate, and show a clear pressed or selected state.
macOS · Windows · Linux
Keep pointer, keyboard, and focus behavior consistent. Common commands can additionally expose a menu item or keyboard shortcut.
watchOS · Wear OS
On a watch, use a short label and a generous target within the small display. Crown or rotary input can supplement touch for adjustable values.
tvOS · Android TV
On TV, give the focused control a prominent visual state and support remote activation; hover and precise pointer targeting are not assumed.
visionOS
In spatial interfaces, use a comfortably targetable control with a clear focus response for indirect gaze-and-pinch interaction.
