Question

如何在下面的轮播示例中添加数字？气泡中应该有数字。现在，在下面的w3学校的代码示例中，它们是空白气泡。

<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="la.jpg" alt="Los Angeles">
    </div>

    <div class="item">
      <img src="chicago.jpg" alt="Chicago">
    </div>

    <div class="item">
      <img src="ny.jpg" alt="New York">
    </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>

这是更新的代码段：

.carousel-indicators li {
  text-indent: 0!important;
  width: 25px!important;
  height: 25px!important;
  margin: 0;
  border-radius: 50px!important;
}
