Tiny Carousel Dots Clustered With No Spacing Between Them
2.5.8 — Target Size (Minimum)
Scenario
Setting
An online spreadsheet's toolbar
What’s wrong
Carousel dots ~8–10px clustered together.
Example
.icon-button { width: 16px; height: 16px; }Why it matters
People with tremor or larger touch contact areas, and anyone tapping on a moving vehicle.
How to test
Measure carousel dot indicators in DevTools: clusters of ~8-10px dots with insufficient spacing 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. .icon-button { width: 24px; height: 24px; } Interactive targets need at least 24 by 24 CSS pixels, or enough spacing that adjacent targets don't overlap that minimum.
Outcome
On an online spreadsheet's toolbar, this barrier is gone for people with tremor or larger touch contact areas — they can complete the task without hitting this wall.
Who is affected
People with tremor or larger touch contact areas, and anyone tapping on a moving vehicle.
