javascript - 以前不使用 Bootstrap Carousel

标签 javascript jquery html css carousel

我在常规屏幕上有一个响应式引导轮播，其中包含 3 个元素(一次移动 1 个)，但是当您按下上一个按钮时，轮播中的图像看起来像是被抛来抛去。有什么办法可以解决这个问题/我做错了什么吗？我似乎无法在脚本中找到错误。

最佳答案

它与媒体浏览器窗口屏幕大小有关。在小屏幕尺寸(例如代码片段)中它可以工作，但是当您在更大的窗口尺寸中测试代码时它不起作用。因此，它与以下事实有关:@media (max-width: 767px) 的样式工作正常，但对于 @media 及以上的样式(例如 @media (min-width: 992px ))，css 标签不是完全的。乍一看，我注意到没有用于更大屏幕尺寸的 .active 标签。
