Question

我正在尝试添加bootstrap轮播，当我检查元素时，dom可用但它没有显示。

我正在使用我从此链接下载的自定义Bootstrap库：

我在模板中遗漏了什么。

这是我试过的：

HTML：

<div id="myCarousel" class="carousel slide" data-ride="carousel">
      <!-- Indicators -->
      <ol class="carousel-indicators">
        <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
        <li data-target="#myCarousel" data-slide-to="1" class=""></li>
        <li data-target="#myCarousel" data-slide-to="2" class=""></li>
      </ol>
      <div class="carousel-inner" role="listbox">
        <div class="item active">
          <img class="first-slide" src="data:image/gif;base64,R0lGODlhAQABAIAAAHd3dwAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==" alt="First slide">
          <div class="container">
            <div class="carousel-caption">
              <h1>Example headline.</h1>
              <p>Note: If you're viewing this page via a <code>file://</code> URL, the "next" and "previous" Glyphicon buttons on the left and right might not load/display properly due to web browser security rules.</p>
              <p><a class="btn btn-lg btn-primary" href="#" role="button">Sign up today</a></p>
            </div>
          </div>
        </div>
        <div class="item">
          <img class="second-slide" src="data:image/gif;base64,R0lGODlhAQABAIAAAHd3dwAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==" alt="Second slide">
          <div class="container">
            <div class="carousel-caption">
              <h1>Another example headline.</h1>
              <p>Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.</p>
              <p><a class="btn btn-lg btn-primary" href="#" role="button">Learn more</a></p>
            </div>
          </div>
        </div>
        <div class="item">
          <img class="third-slide" src="data:image/gif;base64,R0lGODlhAQABAIAAAHd3dwAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==" alt="Third slide">
          <div class="container">
            <div class="carousel-caption">
              <h1>One more for good measure.</h1>
              <p>Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.</p>
              <p><a class="btn btn-lg btn-primary" href="#" role="button">Browse gallery</a></p>
            </div>
          </div>
        </div>
      </div>
      <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
      </a>
      <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
      </a>
    </div>

JS：

$('#myCarousel').carousel();

Fiddle Demo

Answer 1

您的代码中的所有内容都很好，只需要在css下方使用图像高度和宽度就可以解决您的问题。

.carousel-inner > .item >img{
  min-height : 300px;
  max-height : 300px;
  width : 100%;
}

Answer 2

只需要为.container课程提供高度，如下所示：

.container{
  height:300px;
}

但是，我更愿意将container班级名称更改为custom-container。因为bootstrap已经使用container作为类名。因此，远离预期的冲突会更好。
