Success Criterion 2.5.1
Conformance level A

Map or Image Zoomable Only by Pinch Gesture

2.5.1 — Pointer Gestures

Scenario

Setting

A childcare-booking service's scheduling page

What’s wrong

Pinch-to-zoom as the only zoom on maps/images (no +/– controls).

Example

<div ontouchstart="handleSwipe()"></div> <!-- swipe-only delete -->

Why it matters

People with limited hand mobility and users of head-pointers, sticks, or eye-gaze systems.

How to test

Try to zoom a map/image using +/- buttons instead of pinching: if only pinch-to-zoom is offered, it fails.

How to fix

A single-tap/click alternative must exist for every path-based or multi-point gesture.

<div ontouchstart="handleSwipe()"></div>

<button aria-label="Delete item">🗑</button>

Any path-based or multi-touch gesture needs a single-tap alternative that does the same thing.

Outcome

On a childcare-booking service's scheduling page, this barrier is gone for people with limited hand mobility and users of head-pointers — they can finish what they came here to do.
