When to use it​

In Accessible first: Shows how far through the steps a person is.

  • Use it when: A known amount of work: an upload, steps of a form.
  • Not when: A wait of unknown length (spinner), or a layout placeholder (skeleton).

Instead:

  • Spinner: A wait of unknown length.
  • Skeleton: Content that has not arrived.

Words​

  • Use common words. Explain any term you must use.
  • One idea per sentence. Put the action first.
  • Never blame the person.
  • Use: Continue, Change, Start, You. Avoid: Invalid, Utilise, Submit, Error code.

The labels components use, from the voice tokens:

  • content.action.commit: Continue
  • content.action.cancel: Go back
  • content.action.destroy: Delete
  • content.action.retry: Try again
  • content.action.empty-action: Start a new application

See Voice and tone for the whole voice.

Accessibility and keyboard​

Test before you ship:

  • It reports its value and has a name. undefined

Use it in code​

npx open-ds add progress

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

Tokens it reads​

Progress reads 3 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 Progress's tokens to change Progress alone.

Changes with theme

Accessible 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.
