Tooltip

A short hint on hover or focus.

Left out of Content first Readers arrive on any device, and on touch screens hover hints never show. Icons always carry a visible word instead. Use instead: Button, Label

See it live

Start Storybook to see it live: npm run storybook

When to use it

• Use it when: A brief name or hint for a control that already has an accessible name.
• Not when: The only place values or important words live, or touch screens, where hover never happens.

Instead:

• Popover: Opens on click and works on touch.
• Hover card: A richer preview.

How Content first uses it

An icon with no label

Use Not used: always add a word

Not An icon button

Occasional visitors do not know icons.

Words

• Write to one person: "you", not "users".
• Short sentences with room to breathe.
• Explain why before asking for anything.
• Use: Read, Save for later, You, Next issue. Avoid: Click here, Submit, Users, Content.

The labels components use, from the voice tokens:

• content.action.commit: Save
• content.action.cancel: Not now
• content.action.destroy: Remove
• content.action.retry: Try again
• content.action.empty-action: Browse guides

See Voice and tone for the whole voice.

Use it in code

npx open-ds add tooltip

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

Tokens it reads

Tooltip reads 7 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 Tooltip's tokens to change Tooltip alone.

Changes with theme

Content first 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.
