我正在学习bootstrap4。我正在尝试使用引导NAV PILL实现一个结构：一个标签系统（但看起来像按钮），您可以切换标签，在标签下有一个文本内容和一张照片，只有这张照片会显示在左侧，就像标签系统在右边，照片在左边。问题是：1，第一个选项卡处于活动状态，当我单击任何其他选项卡时，什么也没有发生。 2，为什么绝对位置不起作用，照片仍然正确？ 3，如何将文本内容放在标签下，并使标签和内容水平居中对齐？

.rightpart{
  border:2px solid red;
  min-height:100vh;
}
.pillwrapper{
  border:1px solid green;
  min-height:100vh;
}
.container{
  border:1px solid yellow;
  min-height:100vh;
}
.content-photo{
  width:200px;
  left:0;
  top:0;
}

有人可以帮忙吗？

对于Bootstrap 4，“ tabs”实际上是不可标签的，除非您包含JavaScript插件以使Tabs起作用。 Bootstrap的文档指出：

https://getbootstrap.com/docs/4.3/components/navs/#tabs

要查看选项卡的工作原理，请参见Bootstrap文档中的以下链接：

https://getbootstrap.com/docs/4.3/components/navs/#javascript-behavior

以上链接显示了使用与每个选项卡相关的内容的选项卡。要使每个标签下都有内容，每个标签的内容必须具有标签窗格。请参阅Bootstrap文档中的示例。

<ul class="nav nav-tabs" id="myTab" role="tablist">
  <li class="nav-item">
    <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" id="contact-tab" data-toggle="tab" href="#contact" role="tab" aria-controls="contact" aria-selected="false">Contact</a>
  </li>
</ul>
<div class="tab-content" id="myTabContent">
  <div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
  <div class="tab-pane fade" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
  <div class="tab-pane fade" id="contact" role="tabpanel" aria-labelledby="contact-tab">...</div>
</div>

要使标签导航和每个标签下的内容居中，可以使用如下所示的CSS进行标签导航（来自上面的示例HTML）。

.nav {
    display: block;
    margin: 0 auto;
}

有了这些信息，您的HTML应该看起来像这样：

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css" rel="stylesheet" />

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.css" rel="stylesheet" />


<div class="container">

        <ul class="nav">
            <li class="nav-item">
                <a href="#content-1" class="nav-link active" data-toggle="tab">Button 1</a>
            </li>
            <li class="nav-item">
                <a href="#content-2" class="nav-link active" data-toggle="tab">Button 2</a>
            </li>
            <li class="nav-item">
                <a href="#content-3" class="nav-link active" data-toggle="tab">Button 3</a>
            </li>
        </ul>

        <div class="tab-content" id="mypillcontent">

            <div class="tab-pane fade" id="content-1">
                <p>Content Here</p>
                <img src="https://images.pexels.com/photos/162140/duckling-birds-yellow-fluffy-162140.jpeg" alt="" class="content-photo position-absolute" />
            </div>

            <div class="tab-pane fade" id="content-2">
            </div>

            <div class="tab-pane fade" id="content-3">
            </div>

        </div>


    </div>
</div>
