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.
