Hover Preview Card That Vanishes on the Slightest Pointer Move

1.4.13 — Content on Hover or Focus

Scenario

Setting

A car-rental site's checkout flow

What’s wrong

Hover cards (user previews) that vanish on tiny pointer jitter or timeout while being read.

Example

<span title="More info about this field"></span>

Why it matters

Screen-magnifier users, people with motor tremors, and keyboard-only users of tooltips/menus.

How to test

Hover to trigger a user-preview/hover card and try to read it: if it disappears on tiny pointer jitter or times out before you finish reading, it fails.

How to fix

Hover/focus-triggered content must stay visible until dismissed, be dismissible with Esc without moving pointer/focus, and remain when the pointer moves onto it.

<button aria-describedby="tip-1">ⓘ</button>

<div id="tip-1" role="tooltip">More info about this field</div>

A hover-triggered tooltip must be dismissible, stay put while the pointer moves onto it, and stay visible until dismissed.

Outcome

On a car-rental site's checkout flow, this barrier is gone for screen-magnifier users, people with motor tremors — they can complete the task without hitting this wall.
