这意味着您的每个转盘项目都有活动类，只有一个项目应该处于活动状态，而这是将首先显示的项目。要像@Dont Panic所说的那样制作动态旋转木马，您只需为所有项目选择一个活动项目

您的所有项目都处于活动状态，只有一个项目应处于活动状态。我打赌你的内联样式会把事情搞砸-试着去掉图像上的最大宽度和宽度。我也试着删除活动的，我的所有图像现在都消失了。你不应该完全删除活动的。我说应该只有一个。如果将它们全部删除，则没有图像处于活动状态，因此第一张幻灯片中不会显示任何图像！对不起，我的不好，现在我怎样才能下一个/上一个旋转木马？它现在仍然有效。我想你在上一次评论中输入了一个错误，所以我不确定你的意思。需要明确的是：1垂直对齐与正常水平旋转木马的原始问题是否已解决？下一个/上一个呢？

4 images are active
2 images are inactive/deactivate
