Rule: Radio button and checkbox target size (Enhanced)

Rule ID	Target Size 6
Conformance	Recommended
Definition	Radio button and checkbox activation areas are at least 44 by 44 CSS pixels.
Purpose	The intent of this success criterion is to help users who may have trouble activating a small target because of hand tremors, limited dexterity or other reasons. If the target is too small, it may be difficult to aim at the target. Mice and similar pointing devices can be hard to use for these users, and a larger target will help them greatly in having positive outcomes on the web page.
