What is this?

fadeIn/fadeOut animate opacity then adjust display; fadeToggle flips. Good for toasts and soft panels when motion is brief.

Why should you care?

QueryVerse success toasts should appear and leave without jarring jumps.

What happened?

  • Always consider .stop() before re-triggering fades.
  • Prefer CSS transitions for complex motion.
  • Keep durations under ~300ms for UI chrome.

Practice next

  1. Click Show toast repeatedly and observe stop behavior.
  2. Remove delay and compare.
  3. Try fadeToggle on a help panel.
  4. fadeTo(200, 0.5) for dimming a modal backdrop.
  5. Respect reduced motion with a CSS media query later.

Remember

fade* animates opacity. stop queues before re-entry. Short durations feel snappy.

UPI success toast

A PhonePe merchant QueryVerse settlement screen flashes “Payment recorded” after each confirm.

Outcome: fadeIn + delay + fadeOut gives readable, non-blocking feedback.
