What Is a Toggle?
A toggle is a pin passed through the eye of a rope to fasten it, or a switch that turns something on or off. It may also refer to a software or hardware function that is turned on or off through an interaction with a user interface. For example, the caps lock and num lock keys are toggles in computer technology.
In the web, toggles are used to control responsive design. They are especially useful for controlling the display of content based on screen size or device type. For example, a toggle can be set to show or hide navigation menus and sidebars on mobile devices. This allows designers to create more responsive websites that adapt to the device and screen size of the user.
Despite their popularity, toggles have some drawbacks. First, they can be confusing to users. This is because toggles have no empty state and only a left or right side. Toggle switches are often colored to help differentiate them, but this doesn’t always work, particularly for people with color blindness. For example, using green to indicate “on” and red to indicate “off” can be very confusing for some people with color vision deficiency.
Another problem with toggles is that they can lead to messy code. If a toggle isn’t properly implemented, it can result in a lot of if-else statements. To avoid this, it is best to follow some basic principles when creating a toggle.
