When to use it

In Brand expressive: A product preview that opens on tap.

• Use it when: Extra detail or a small control next to what it explains, on any device.
• Not when: A one-line hint (tooltip), or a task that should block the page (dialog).

Instead:

• Tooltip: A one-line hint on hover.
• Dialog: A blocking task.

Words

• Headlines are short and bold. Three to six words.
• Verbs that move: Join, Try, Go.
• Playful in headlines, plain in errors.
• Use: Join, Drop, Go, Love. Avoid: Synergy, Leverage, Kindly.

The labels components use, from the voice tokens:

• content.action.commit: Go
• content.action.cancel: Not now
• content.action.destroy: Remove
• content.action.retry: Try again
• content.action.empty-action: Explore the drop

See Voice and tone for the whole voice.

Use it in code

npx open-ds add popover

The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.

Tokens it reads

Popover reads 10 tokens of its own, each an alias of a semantic token. Each row is one part: its own token, the semantic it aliases, and the value it ends at. Change a semantic and every component that reads it follows; override one of Popover's tokens to change Popover alone.

Changes with theme

Brand expressive decides what changes when you switch theme. Here a switch changes colors only, so the marked rows differ between light and dark; everything else holds steady.
