Question

由于我正在使用Bootstrap 4本机类创建两个包含内容的选项卡窗格，所以我想知道是否有特定的类使两个内容窗格（类.tab-pane）的高度相等？

我的html是：

<div class="d-flex flex-column">
    <ul class="nav nav-pills">
        <li class="nav-item">
            <a class="nav-link active show" data-toggle="pill" href="#first">ONE</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" data-toggle="pill" href="#second">TWO</a>
        </li>
    </ul>
    <div class="tab-content">
        <div class="tab-pane container active show" id="first">        
            // content
        </div>
        <div class="tab-pane container fade" id="second">
            // content
        </div>
    </div>
</div>

如果没有，即使是某些CSS来解决也很酷，我尝试在外部div上使用flex: 1 1 auto并在两个窗格上使用flex: 1 0 100%，但是也不起作用。

您可以使用Tabs with consistent height CSS Trick。

需要进行以下更改：

对于不活动的标签页，使用visibility: hidden;代替display: none;
在标签容器中使用display: flex;
为标签窗格设置width: 100%;和margin-right: -100%;

将它们放在一起：

.consistent-height .tab-content {
  display: flex;
}

.consistent-height .tab-content > .tab-pane {
  display: block; /* undo "display: none;" */
  visibility: hidden;
  margin-right: -100%;
  width: 100%;
}

.consistent-height .tab-content > .active {
  visibility: visible;
}

    </li>
    <li class="nav-item">
      <a class="nav-link" id="tab-two" data-toggle="tab" href="#two" role="tab" aria-controls="profile" aria-selected="false">Two</a>
    </li>
  </ul>
  <div class="tab-content" id="myTabContent">
    <div class="tab-pane fade show active" id="one" role="tabpanel" aria-labelledby="tab-one">
      One line
    </div>
    <div class="tab-pane fade" id="two" role="tabpanel" aria-labelledby="tab-two">
      Two<br>lines
    </div>
  </div>
  <div class="alert alert-warning mt-3" role="alert">
    This box is not jumping around when switching tabs. The box position is adapted when the container width changes.
  </div>
</div>

您可以在类tab-content中使用属性min-height。

例如，我以像素为单位使用值，建议您使用百分比或在rem或em中应用值，如您所愿。

.tab-content {
  background-color: yellow; /*Only for visual example*/
  min-height: 100px;
}

由于无法找到适合我的解决方案，因此我写了自己的解决方案：

  maxheight = 0;
  tabs = jQuery('.tab-content .tab-pane');
  jQuery.each(tabs, function() {
      this.classList.add("active"); /* make all visible */
      maxheight = (this.clientHeight > maxheight ? this.clientHeight : maxheight);
      if (!jQuery(this).hasClass("show")) {
          this.classList.remove("active"); /* hide again */
      }
  });
  jQuery.each(tabs, function() {
      jQuery(this).height(maxheight);
  });

Bootstrap 4如何等于两个标签窗格的高度？
