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 for actionable items
Placing ‘clickable’ items in close proximity can cause difficulties. Users with motor disabilities may lack fine motor control and find it difficult to click the correct item. Touch screen device users may also errantly activate the wrong thing. Additional whitespace around buttons and links, and increasing the line spacing for lists of links can help all users accurately activate the correct actionable item.
