Bootstrap轮播照片列表不起作用

Question

我正在尝试在这个网站上添加一个引导程序轮播，我正在为某人制作，每次添加照片或标题时，这些照片都会排列在列表中，并且标题会叠加在一起。有人可以帮忙吗？

这就是网站的样子：

照片堆叠在一起：

使用<h3>和<h4>字符串的标题是什么样的：

这是一些代码（我使用了bootstrap在他们网站上的模板）：

<section class="container">
      <div class="row">
        <div class="col-sm-12">
          <div id="my-slider" class="carousel slide col-sm-12" data-ride="carousel">
            <!-- indicators -->
            <ol class="carousel-indicators">

              <li data-target="#my-slide" data-slide-to="1"></li>
              <li data-target="#my-slide" data-slide-to="2"></li>
              <li data-target="#my-slide" data-slide-to="3"></li>

Answer 1

在bootstrap 4中，每个幻灯片应该有一个类carousel-item而不是item作为bootstrap 3，

同样@WebDevbooster提到bootstrap 4不包括字体awsome所以为你控制使用qazxsw poi进行上一级控制和下一轮carousel-control-next：

见下面的工作片段：

carousel-control-prev

.carousel-inner img {
      width: 100%;
      height: 100%;
  }

Answer 2

不允许将Bootstrap列直接嵌套在其他Bootstrap列中。

Bootstrap列必须始终具有Bootstrap

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

<section class="container">
      <div class="row">
        <div class="col-sm-12">
          <div id="my-slider" class="carousel slide" data-ride="carousel">
            <!-- indicators -->
            <ol class="carousel-indicators">
              <li data-target="#my-slider" data-slide-to="0" class="active"></li>
              <li data-target="#my-slider" data-slide-to="1"></li>
              <li data-target="#my-slider" data-slide-to="2"></li>
              <li data-target="#my-slider" data-slide-to="3"></li>
            </ol>
            <!-- wrappers -->
            <div class="carousel-inner" role="listbox">
              
              <div class="carousel-item active">
                  <img id="img" src="https://www.w3schools.com/bootstrap4/chicago.jpg" alt="siku"/>

                  </div>
                </div>
                <div class="carousel-item">

                  </div>
                </div>
                <div class="carousel-item">
                  <img id="img" src="https://www.w3schools.com/bootstrap4/la.jpg" alt=""/>
                  <div class="carousel-caption">
                    <h4></h4>
                    <h5></h5>
                  </div>
                </div>

                      <h4></h4>
                      <h5></h5>
                    </div>
                  </div>
            </div>
            <!-- controls -->
              <!-- Left and right controls -->
  <a class="carousel-control-prev" href="#my-slider" data-slide="prev">
    <span class="carousel-control-prev-icon"></span>
  </a>
  <a class="carousel-control-next" href="#my-slider" data-slide="next">
    <span class="carousel-control-next-icon"></span>
  </a>
          </div>
        </div>
      </div>
    </section>

作为父级。

参考：

row

此外，Bootstrap 4中没有glyphicons。
