Accordion - Lightning Design System

An accordion allows a user to toggle the display of a section of content.

Base

Selector: The CSS class being referred to.
Summary: A description of what the class does.
Support: Whether the class name is dev-ready (meaning it's fully vetted and tested and safe to use) or prototype (which means it's not fully vetted yet).
Restrict: The selector that the class name is allowed to be used on.
Variant: The base level pattern for a component. A variant can be extended to create another variant of that component, for example, a stateful button is a derivative of the base button.
Modifier: A single class that can be added to an HTML element of a component to modify its output. Typically these will be colors, sizing and positioning.
