Component Deep Dive #17: Toast Notification — 4 Seconds That Make or Break UX

Toast Notification — 4 Seconds That Make or Break UX

A user clicks a button, sees nothing happen, clicks three more times — and crashes the page. The missing ingredient? Feedback. Toast notifications are the web's lightest feedback mechanism: appear, inform, disappear.

Key Implementation

Use CSS animation (not transition) for entry/exit — dynamically inserted DOM elements need animation to trigger automatically. Set aria-live="polite" so screen readers announce the toast without interrupting.

Variants

  • Stacking toasts: newest on top with auto-dismiss for old ones
  • Swipe-to-dismiss on mobile
  • Action toasts: include "Undo" button within the 4-second window
