Question

我有一个带引导程序4的buttongroup，一切都很好

<div class="btn-group" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-outline-secondary">Left</button>
  <button type="button" class="btn btn-outline-secondary">Middle</button>
  <button type="button" class="btn btn-outline-secondary">Right</button>
</div>

如何更多地突出显示所选状态？例如。我想要一个活动按钮的红色背景颜色。

如果您将data-toggle="button"应用于包装器元素，则子按钮会自动将.active应用于单击的任何按钮。

注意：此.active类可应用于组中的任意数量的<button>元素;如果您的目的是使.active唯一，那么您可能需要使用一些JavaScript来扩展它。
