如何在 bootstrap3 轮播滑块中添加 icons/images 作为指示器而不是列表圆圈

How to add icons/images as indicators rather than list circles in bootstrap3 carousel slider

您好,我正在尝试制作一个 bootstrap3 旋转木马滑块,我想添加一些图像作为幻灯片指示器而不是列表默认圆圈。

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>

如果我添加如下 img 标签:

<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>

它没有显示任何内容。如何实现添加图像作为指示器而不是

  • 圆圈?

  • 我认为最重要的是覆盖 .carousel-indicators.

    li 标签的 widthheight 属性

    为此,我创建了一个名为 .carousel-indicators--thumbnails 的附加修饰符 css class,并将其添加到 .carousel-indicators div。此修饰符 class 用于覆盖 li.active.active .thumbnail class.

    .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;
    }
