将旋转木马垂直居中放置在一个区段内


我有一个真正基本的闪烁旋转木马与一些图像。 我的问题是它在页面的顶部铰链，我想把整个旋转木马的中心垂直在我的部分。 我的部分的高度等于我的设备的高度，所以它基本上是全屏的。 我试了这么多，但我不知道如何解决它。 我试图在我的分区上应用display:flex；和align-items:center；技巧，但它破坏了整个轮播。。。

我的代码:

您的section块正确对齐，而div.carousel则没有正确对齐。

我已经解决了这个问题，使用了额外的包装元素-div.center-wrap。 风格也改变了:

.carousel {
  background: #0b1320;
  width: 100%;
}
div.center-wrap {
  display: flex;
  justify-content: center;
  align-items: center;
  min-height: 100vh;
}
