在小型设备上一排显示轮播

Question

这是来自codepen的示例引导程序轮播，这是来自bootsnip的示例。它们中的大多数都遵循这样的典型 HTMl 结构。

<div class="carousel slide" data-ride="carousel" data-type="multi" data-interval="3000" id="myCarousel">
  <div class="carousel-inner">
    <div class="item active">
      <div class="col-md-2 col-sm-6 col-xs-12"><a href="#"><img src="img1.png" class="img-responsive"></a></div>
    </div>
    <div class="item">
      <div class="col-md-2 col-sm-6 col-xs-12"><a href="#"><img src="img2.png" class="img-responsive"></a></div>
    </div>
    </div>
  </div>
  <a class="left carousel-control" href="#myCarousel" data-slide="prev"><i class="glyphicon glyphicon-chevron-left"></i></a>
  <a class="right carousel-control" href="#myCarousel" data-slide="next"><i class="glyphicon glyphicon-chevron-right"></i></a>
</div>
</div>

这些在桌面上运行良好，因为它们会生成这样的轮播：

但是切换到移动设备，轮播会分成多行，如下所示：

这不是我想要的行为，因为如果图像占用多行空间，使用轮播的目的就失去了。

在移动设备上，我希望一次只显示一个产品（在一行中），随后的产品在单击左侧或右侧轮播控件时显示。

我怎么做 ？

Answer 1

我同意其他人的看法，最好使用其他插件来实现此功能。我建议owlcarousel2。如果你想要一个只有引导程序的解决方案，这里是一个实现。
