在部分内垂直居中旋转木马

Question

我有一个非常基本的 Flickity 旋转木马，里面有一些图片。我的问题是它停留在页面顶部，我想将整个旋转木马垂直居中放置在我的部分内。我的部分高度等于我的设备的高度，所以它基本上是全屏的。我尝试了很多东西，但我不知道如何解决。我试图在我的部分应用 display:flex; 和 align-items:center; 技巧，但它破坏了整个旋转木马...

我的代码：

**style.css** ```
/* external css: flickity.css */

* {
  box-sizing: border-box;
}

body {
  font-family: sans-serif;
}

#section-b {
  padding: 0px;
  margin: 0px;
  background: #0b1320;
  text-align: center;
  color: white;
  min-height: 100vh;
}

.carousel {
  background: #0b1320;
}

.carousel-cell {
  width: 70%;
  height: 200px;
  /* flex-box, center image in cell */
  display: -webkit-box;
  display: -webkit-flex;
  display: flex;
  -webkit-box-pack: center;
  -webkit-justify-content: center;
  justify-content: center;
  -webkit-align-items: center;
  align-items: center;
}

.carousel-cell img {
  display: block;
  max-width: 100%;
  max-height: 100%;
  /* dim unselected */
  opacity: 0.7;
  -webkit-transform: scale(0.85);

  transition: opacity 0.3s, transform 0.3s, filter 0.3s;
}


/* brighten selected image */

.carousel-cell.is-selected img {
  opacity: 1;
  -webkit-transform: scale(1);
  transform: scale(1);
  -webkit-filter: none;
  filter: none;
}

@media screen and (min-width: 768px) {
  .carousel-cell {
    height: 400px;
  }
}

@media screen and (min-width: 960px) {
  .carousel-cell {
    width: 60%;
  }
}


/* buttons, no circle */

.flickity-prev-next-button {
  width: 60px;
  height: 60px;
  background: transparent;
  opacity: 0.6;
}

.flickity-prev-next-button:hover {
  background: transparent;
  opacity: 1;
}


/* arrow color */

.flickity-prev-next-button .arrow {
  fill: white;
}

.flickity-prev-next-button.no-svg {
  color: white;
}


/* closer to edge */

.flickity-prev-next-button.previous {
  left: 0;
}

.flickity-prev-next-button.next {
  right: 0;
}


/* hide disabled button */

.flickity-prev-next-button:disabled {
  display: none;
}

您的 section 块已正确对齐，而 div.carousel 未正确对齐。

我已经解决了这个问题，使用额外的包装器元素 - div.center-wrap。样式也已更改：

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