如何在Bootstrap3轮播滑块中添加图标/图像作为指示符而不是列表圆

嗨，我正在尝试制作bootstrap3旋转木马滑块，我想添加一些图像作为滑块指示器，而不是列表默认圆。

HTML标记：

<div id="carousel-slider" class="carousel slide" data-ride="carousel" data-interval="5000">

            <!-- Slider Indicators -->
            <ul class="carousel-indicators">
                <li data-target="#carousel-slider" data-slide-to="0" class="active"></li>
                <li data-target="#carousel-slider" data-slide-to="1"></li>
                <li data-target="#carousel-slider" data-slide-to="2"></li>
            </ul><!--/ Indicators end-->
</div>

如果我添加一个img标签，如下所示：

<div id="carousel-slider" class="carousel slide" data-ride="carousel" data-interval="5000">

            <!-- Slider Indicators -->
            <ul class="carousel-indicators">
                <li data-target="#carousel-slider" data-slide-to="0" class="active">
                    <div class="thumbnail">
                        <img class="img-responsive" src="https://s3.amazonaws.com/ooomf-com-files/wdXqHcTwSTmLuKOGz92L_Landscape.jpg">
                    </div></li>
                <li data-target="#carousel-slider" data-slide-to="1"></li>
                <li data-target="#carousel-slider" data-slide-to="2"></li>
            </ul><!--/ Indicators end-->
        <div>

它什么也没显示。如何实现将图像添加为指标而不是添加

圆圈？

我认为最重要的是重写内标签的width和height属性。li.carousel-indicators

为此，我创建了一个名为的附加修饰符css类.carousel-indicators--thumbnails，该类已添加到中.carousel-indicators div。这个修改类用于重写li，.active和.active .thumbnail类。

.carousel-indicators.carousel-indicators--thumbnails li {
  width: 80px;
  height: 40px;
  margin: 0;
  border: none;
  border-radius: 0;
}
.carousel-indicators.carousel-indicators--thumbnails .active {
  background-color: transparent;
}
.carousel-indicators.carousel-indicators--thumbnails .active .thumbnail {
  border-color: #337ab7;
}
