弹性框垂直居中对齐问题（对齐项目：居中）

Question

我希望导航箭头垂直居中。

在 live site 上它们偏离了中心。

存在妥协 CSS 我无法更改为箭头设置 top: 40% (.owl-nav button)。

我试过 unset他们的顶部，但这会将他们推到图像下方。

我试过设置 top: calc(50% - 37.5px);（减去按钮高度 75px 的一半），但这是偏离中心的。我的数学在这里吗？

我已经能够通过为 .owl-nav.pp-carousel-nav 使用固定高度来让它在下面工作，但是在 live page 上 .owl-items 不是固定的宽度和高度，它们反应灵敏。

.owl-carousel .owl-stage {
  position: relative;
}
.pp-content-post-carousel {
  position: relative;

Answer 1

button 的 height 是 66px，相对于 div 和 class="pp-content-post-carousel pp-equal-height clearfix" 的位置比图像高 33.19px。

Answer 2

这里是评论中的答案：

问题是由导航元素父框引起的。它还包括下面的文本 - 因此，您不会将它相对于图像居中，而是相对于图像及其描述性文本居中。由于您可能无法在此处更改 html 结构，因此我建议您只需将 css 计算更改为

top: calc(50% - 45px);
