Use Case
Build a Notification System with React and Tailwind CSS v4
Build an accessible notification system with toast messages and inline alerts — using Ninna UI's Alert and Toast components and Tailwind v4.
Notifications and accessibility
Notifications need to be announced to screen reader users. Use aria-live="polite" for non-urgent notifications (toasts) and aria-live="assertive" for urgent ones (errors). Ninna UI's Toast component handles this automatically.
1. Inline alerts with Alert
Use the Alert component from @ninna-ui/feedback for inline messages:
import { Alert } from "@ninna-ui/feedback";
<Alert variant="success" title="Saved!"> Your changes have been saved successfully.</Alert>
<Alert variant="danger" title="Error"> Failed to save. Please try again.</Alert>2. Toast notifications
Use the Toast component from @ninna-ui/feedback for temporary notifications:
import { Toast } from "@ninna-ui/feedback";import { Button } from "@ninna-ui/primitives";
<Toast> <Toast.Trigger asChild> <Button color="primary">Save</Button> </Toast.Trigger> <Toast.Content title="Saved!" description="Your changes have been saved." /></Toast>3. Toast with action button
Add an action button (like Undo) to the toast:
<Toast.Content title="Item deleted" description="The item was removed."> <Toast.Action altText="Undo" onClick={handleUndo}> Undo </Toast.Action></Toast.Content>
