Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Banner | Choose banner when the message scope spans multiple pages, sections, records, or sessions in the same product, service, account, or workspace. | The banner appears before users encounter content affected by the message. | GOV.UK describes notification banners for broad service problems, personal deadlines, and previous-page outcomes, with placement before the page heading and sparing use. |
| Notification banner | Choose notification banner when a service message should be seen immediately before the page heading and before users interpret that page. | The banner appears before the page H1 and in the same content width as the heading and body text. | GOV.UK defines notification banner use for service-wide problems, personal deadlines, previous-page outcomes, before-H1 placement, role selection, sparing use, and validation-error avoidance. |
| Success confirmation | Choose success confirmation when the user needs durable in-context proof that a just-completed action succeeded. | The confirmation appears only after the action is committed enough to be truthful. | GOV.UK describes green success notification banners for outcomes of just-completed actions when the current journey continues. |
