9.17 WCAG 2.2 Success Criterion 2.5.8 － Target Size (Minimum)

Ensure that all targets meet a minimum size of at least 24 by 24 CSS pixels or have sufficient spacing around them. Make controls easier to activate.

Before Rectification

The example above having undersize targets with insufficient space (24 by 24 CSS pixels), user find it difficult to accurately activate the button that are too close.

After Rectification

Sufficient space (24 by 24 CSS pixels) provided between undersize targets, reduce the likelihood of accidentally clicking the wrong button.
