Countdown Timer Update Shown Visually but Never Announced

4.1.3 — Status Messages

Scenario

Setting

A budget airline's flight search results

What’s wrong

Countdown/timer status text (resend-one-time password (OTP) timers, session countdowns) updating visually only.

Example

<div id="cart-status">Item added</div> <!-- silent DOM update -->

Why it matters

Screen-reader users who need spoken confirmation of saves, errors, and results.

How to test

Watch a countdown/timer (e.g., resend-OTP, session countdown) with a screen reader running: if the changing time isn't announced, it fails.

How to fix

The status text must be wired as a live region (code that makes screen readers announce updates)/status role so screen readers announce it automatically without moving focus.

<div id="cart-status" role="status" aria-live="polite">Item added</div>

role="status" with aria-live announces the update to screen reader users without moving their focus.

Outcome

On a budget airline's flight search results, this barrier is gone for screen-reader users who need spoken confirmation of saves, errors — they no longer have to work around this.
