html - 为什么这个 Bootstrap 轮播不工作？

Question

IMAGE IS WHAT I SEE
试图让这个旋转木马工作。我尝试过 CSS 和其他想法，但没有用。

ERROR: The photos are shown one after the other and are not in"carousel" style. It looks like I just slapped the pictures onto thecode, there's no carousel at all.

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>

你的类名有一些错误。 item 应该是 carousel-item，left carousel control 应该是 carousel-control-prev 等等。

修复这些应该会给你想要的结果:
