Question

IMAGE IS WHAT I SEE尝试使该轮播工作正常，最初有什么问题吗？我尝试了CSS，并查看了其他问题，以了解为什么它不起作用但我看不到错误。也许会新鲜的眼睛。

错误：照片一张一张接一张显示，并且不是“旋转木马”风格。好像我只是将图片拍到代码上一样，根本没有旋转木马。

这是我的代码：

     <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"></li>
    <li data-target="#myCarousel" data-slide-to="2"></li>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner">
    <div class="item active">
        <img src="couple-walking-dog-in-front-of-well_orig.jpg" />
    </div>

    <div class="item">
        <img src="th.jpg" />
    </div>

    <div class="item">
        <img src="victory-girl_orig.jpg" />
    </div>
  </div>

  <!-- Left and right controls -->
  <a class="left carousel-control" href="#myCarousel" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#myCarousel" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

Answer 1

您的班级名称有一些错误。 item应该是carousel-item，left carousel control应该是carousel-control-prev等。

修复这些问题应该会为您带来预期的结果：

Answer 2

您似乎错过了班级名称。您的代码

  <div class="carousel-inner">
    <div class="item active">

看起来最后一个类应该是：“ carousel-item active ”，而不仅仅是：“ item active ”

为什么此自举轮播无法正常工作？
