- Success Criterion 2.1.1
- Conformance level A
Action That Only Works With a Double-Click
2.1.1 — Keyboard
Scenario
Setting
A ride-hailing app's trip booking screen
What’s wrong
Double-click-only activations.
Example
<div onclick="submitForm()">Submit</div>Why it matters
Blind users, people with motor disabilities, and anyone operating the interface without a pointer.
How to test
Tab to the control and press Enter once: if activation requires a double-click and single Enter does nothing, it fails.
How to fix
Trigger on single click/Enter — never require double-click as the only activation.
<button onclick="submitForm()">Submit</button>A native button is focusable and triggers on Enter/Space automatically; a div needs all of that added by hand.
Outcome
On a ride-hailing app's trip booking screen, this barrier is gone for blind users, people with motor disabilities — they no longer have to work around this.
Who is affected
Blind users, people with motor disabilities, and anyone operating the interface without a pointer.
