Some things are either on or off and, when those things aren’t on (or off), they are invariably off (or on). The concept is so rudimentary that I’ve only complicated it by trying to explain it, yet on/off switches (or toggle buttons) are not all alike. Although their purpose is simple, their applications and forms vary greatly.
In this inaugural post, I’ll be exploring what it takes to make toggle buttons inclusive. As with any component, there’s no one way to go about this, especially when such controls are examined under different contexts. However, there’s certainly plenty to forget to do or to otherwise screw up, so let’s try to avoid any of that.
