Offered as a service from the WebAIM website, Maine CITE provides the following “tip” on how to make your website more accessible to all people.
Spacing between clickable elements
If adjacent links, buttons, checkboxes, or other controls are too close, they can be difficult to accurately activate for users who may not have fine motor control, those using small-screen mobile devices, or others. Ensure that clickable elements have adequate spacing between them. For small clickable elements, such as checkboxes, ensure that there is a sufficiently large clickable area, including the associated form control label.
