v0.21.0AlphaReviewed for accessibility

Description

A Dialog is used to remove the user from the main application flow, to confirm actions, ask for disambiguation or to present small forms.

Accessibility

  • Dialog Accessible Name: A dialog should have an accessible name, so screen readers are aware of the purpose of the dialog when it opens. Give an accessible name setting :title. The accessible name will be used as the main heading inside the dialog.
  • Dialog unique id: A dialog should be unique. Give a unique id setting :dialog_id. If no :dialog_id is given, a default randomize hex id is generated.

The combination of both :title and :dialog_id establishes an aria-labelledby relationship between the title and the unique id of the dialog.
