垂直居中 Bootstraps col 中的内容

Question

当我尝试将 Bootstrap 列中的某些内容垂直居中时遇到一些问题。

在这个例子中，我喜欢将高度为 50vh 的 page-hws 部分的全部内容垂直居中。

leitbild 部分中的相同问题。我无法将文本垂直居中。

.page-hws {
  height: 50vh;
}
.hws {
  position: relative;
  z-index: 10;
  background-color: #fff;
  display: table;
}
.hws-icon {
  display: block;
  margin-right: auto;
  margin-left: auto;
  width: 80%;
  height: 80%;
  max-height: 200px;
  max-width: 200px;
}
.hws-fact {
  color: #000;
  font-size: 2em;
  font-family: 'Raleway';
  font-weight: 500;
  text-align: center;
  padding-bottom: 0.5em;
  display: inline;
}
.hws-fact-container {
  text-align: center;
}
.hws-hashtag {
  font-family: 'Raleway';
  color: #e28634;
  text-transform: uppercase;
  font-size: 1.3em;
  font-weight: 800;
  text-align: center;
}
.hws-fact-line {
  padding-top: 0.3em;
  font-family: 'Arvo';
  color: #000;
  font-size: 1em;
  font-weight: 500;
  text-align: center;
}
.hws-text-title {
  font-family: 'Arvo';
  color: #000;
  text-transform: uppercase;
  font-size: 1.5em;
  font-weight: 800;
}
.leitbild-text {
  width: 100%;
  color: #fff;
  font-family: 'Raleway', Sans-Serif;
  font-weight: 800;
  font-size: 2.5em;
  text-transform: uppercase;
  display: table-cell;
  vertical-align: middle;
}
.leitbild-container {
  padding: 0;
  margin: 0;
  position: relative;
  z-index: 4;
}
.carousel-indicators li {
  background-color: #fff;
  border: none;
}
.carousel-indicators .active {
  background-color: #f4980b;
  border: none;
}
.overlay {
  position: absolute;
  top: 0;
  bottom: 0;
  right: 0;
  left: 0;
  background-color: rgba(15, 32, 59, 0.9);
  padding: auto;
  margin: auto;
  text-align: center;
}

Answer 1

试试这个

.page-hws {
  height: 50vh;
  display: table;
}

.hws {
  position: relative;
  z-index: 10;
  background-color: #fff;
  display: table-cell;
  vertical-align: middle;
}

Answer 2

如何给 .hws 页面一个 position:relative 和 .hws position:absolute.

body,html {
    /* necessary */
    height:100%;
}

.page-hws {
  height: 100%;
  position: relative;
}
.hws {
  position: absolute;
  top:50%;
  z-index: 10;
  background-color: #fff;
  display: table;
}
