Question

我已经根据一些教程构建了一个带引导程序的轮播。它在我的笔记本电脑的屏幕上工作正常，即使我调整窗口大小，但是一旦我在智能手机上打开它，旋转木马就会丢失，所有我看到的都是指示箭头和图像替代文字。

代码很标准，但在这里：

<div class="carousel-inner" role="listbox">
                <div class="item active">
                  <img src="http://s1.picswalls.com/wallpapers/2016/03/29/beautiful-nature-wallpaper_042325903_304.jpg" alt="portfolio1">
                  <div class="carousel-caption">
                    <h1>Portfolio1</h1>
                  </div>
                </div>
                <div class="item">
                  <img src="http://s1.picswalls.com/wallpapers/2016/03/29/beautiful-nature-wallpaper_042325903_304.jpg" alt="portfolio1">
                  <div class="carousel-caption">
                    <h1>Portfolio2</h1>
                  </div>
                </div>
                <div class="item">
                  <img src="http://s1.picswalls.com/wallpapers/2016/03/29/beautiful-nature-wallpaper_042325903_304.jpg" alt="portfolio1">
                  <div class="carousel-caption">
                    <h1>Portfolio3</h1>
                  </div>
                </div>
              </div>

是否还有其他课程，教程忘记提及或者我需要在CSS上做一些工作吗？希望你能帮帮我。

非常感谢

您是否添加了jquery.min文件的链接？或提供网站链接

如果您使用的是最新的bootstrap 4 beta，那么您需要将“item”替换为“carousel-item”。

这是您的代码与示例轮播合并https://getbootstrap.com/docs/4.0/components/carousel/#with-indicators

<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
  </ol>
<div class="carousel-inner" role="listbox">
            <div class="carousel-item active">
              <img src="http://s1.picswalls.com/wallpapers/2016/03/29/beautiful-nature-wallpaper_042325903_304.jpg" alt="portfolio1">
              <div class="carousel-caption">
                <h1>Portfolio1</h1>
              </div>
            </div>
            <div class="carousel-item">
              <img src="http://s1.picswalls.com/wallpapers/2016/03/29/beautiful-nature-wallpaper_042325903_304.jpg" alt="portfolio1">
              <div class="carousel-caption">
                <h1>Portfolio2</h1>
              </div>
            </div>
            <div class="carousel-item">
              <img src="http://s1.picswalls.com/wallpapers/2016/03/29/beautiful-nature-wallpaper_042325903_304.jpg" alt="portfolio1">
              <div class="carousel-caption">
                <h1>Portfolio3</h1>
              </div>
            </div>
          </div>
  <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
