How to get button groups that span the full width of a parent in Bootstrap?

In Bootstrap, how can I get a button group like the following that span the full width of a parent element? (like with the ".btn-block" class, but applied to a group http://getbootstrap.com/css/#buttons-sizes )

<div class="btn-group" role="group" aria-label="...">
  <button type="button" class="btn btn-default">Left</button>
  <button type="button" class="btn btn-default">Middle</button>
  <button type="button" class="btn btn-default">Right</button>
</div>
Solution

  • Flexbox can do that.

    .btn-group.special {
  display: flex;
}

.special .btn {
  flex: 1
}
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />
<div class="btn-group special" role="group" aria-label="...">
  <button type="button" class="btn btn-default">Left</button>
  <button type="button" class="btn btn-default">Middle</button>
  <button type="button" class="btn btn-default">Right</button>
</div>
