// Button groups
// --------------------------------------------------


// Make the div behave like a button
.btn-group {
  margin-right: 3px;
  position: relative;
  white-space: nowrap; // prevent buttons from wrapping when in tight spaces (e.g., the table on the tests page)
}

// Optional: Group multiple button groups together for a toolbar
.btn-toolbar {
  .btn-group {
    display: inline-block;
  }
  * {
    margin-right: 3px;
  }
  *:last-child {
    margin-right: 0;
  }
}

// Float them, remove border radius, then re-add to first and last elements
.btn-group > * {
  border-radius: 0;
  position: relative;
  margin-right: 0;
}
.btn-group > * + * {
  margin-left: -1px;
}

// Set corners individual because sometimes a single button can be in a .btn-group and we need :first-child and :last-child to both match
.btn-group > .btn:first-child {
  border-top-left-radius: var(--btn-border-radius, 3px);
  border-bottom-left-radius: var(--btn-border-radius, 3px);
}
// Need .dropdown-toggle since :last-child doesn't apply given a .dropdown-menu immediately after it
.btn-group > .btn:last-child,
.btn-group > .dropdown-toggle {
  border-top-right-radius: var(--btn-border-radius, 3px);
  border-bottom-right-radius: var(--btn-border-radius, 3px);
}

// On hover/focus/active, bring the proper btn to front
.btn-group > .btn:hover,
.btn-group > .btn:focus,
.btn-group > .btn:active,
.btn-group > .btn.active {
  z-index: 2;
}
