Toolbar Icons Packed Edge to Edge With No Gap

2.5.8 — Target Size (Minimum)

Scenario

Setting

A hospital's patient portal appointment scheduler

What’s wrong

Toolbar icon rows (rich text editors) at 20px with zero gap.

Example

On a hospital's patient portal appointment scheduler: toolbar icon rows (rich text editors) at 20px with zero gap.

Why it matters

People with tremor or larger touch contact areas, and anyone tapping on a moving vehicle. On a hospital's patient portal appointment scheduler specifically, they lose track of where they are on the page.

How to test

Measure toolbar icon buttons (e.g., in a rich text editor) in DevTools: 20px icons with zero gap between them fail.

How to fix

The target must be at least 24x24 CSS px, or have enough spacing that a 24px circle around its center overlaps no other target, or a compliant equivalent control must exist.

Outcome

Fixed, a visitor to a hospital's patient portal appointment scheduler can reach and operate the control without a mouse.

Who is affected

People with tremor or larger touch contact areas, and anyone tapping on a moving vehicle.
