// Base class
//

  margin-bottom: 0;

// Interactive list items
//
// Use anchor or button elements instead of `li`s or `div`s to create interactive
// list items. Includes an extra `.active` modifier class for selected items.

  width: 100%; // For `<button>`s (anchors become 100% by default though)

// Flush list items
//
// Remove borders and border-radius to keep list group items edge-to-edge. Most
// useful within other components (e.g., cards).

// Contextual variants
//
// Add modifier classes to change text and background color on individual items.
// Organizationally, this must come after the `:hover` states.
