将 prev/next 按钮放在 Bootstrap Carousel 的顶部
Place the prev/next buttons to the top in Boostrap Carousel
在我的应用程序中，我想可视化我的 kMeans 集群，所以我想我可以使用完整的 window 旋转木马，其中每张幻灯片将包含 10(0) 个集群图像。因此，当用户单击下一个按钮时，他应该查看第二个群集等。我会将图像调整为相同大小，但问题是上一个和下一个按钮的平均高度为幻灯片，使用户必须向下滚动才能单击它们，这可能不是他想要的。
那么如何将 prev/next 按钮放在顶部？
我试过这个：
<a class="left carousel-control" href="#mycarousel" role="button" data-slide="prev" style="top: 0"> <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span> <span class="sr-only">Previous</span> </a>
但是什么也没发生！喜欢使用 Splash 的 Magikarp...
我正在使用 Bootstrap 轮播的基本示例。有什么想法吗？
