垂直居中显示内容：flex;列

Question

我正在使用Flexbox来对齐两个相邻列的高度，这是有效的。我现在需要在不使用固定高度的情况下将内部内容垂直居中在柔性框列中。此外，这一切都需要在Bootstrap 3中工作。请参阅下面的代码：

＆＃13;

＆＃13;

.row-flex,
.row-flex > div[class*='col-'] {
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  flex: 1 1 auto;
}
.row-flex-wrap {
  -webkit-flex-flow: row wrap;
  align-content: flex-start;
  flex: 0;
}
.row-flex > div[class*='col-'],
.container-flex > div[class*='col-'] {
  margin: -.2px;
  /* hack adjust for wrapping */
}
.container-flex > div[class*='col-'] div,
.row-flex > div[class*='col-'] div {
  width: 100%;
}
.flex-col {
  display: flex;
  display: -webkit-flex;
  flex: 1 100%;
  flex-flow: column nowrap;
}
.flex-grow {
  display: flex;
  -webkit-flex: 2;
  flex: 2;
}
.content {
  border: 1px solid black;
  padding: 20px;
}
.content-inner {
  border: black solid 1px;
  padding: 20px;
}
.img {
  width: 100px;
  height: auto;
  display: block;
  margin: 0 auto;
}
figcaption {
  text-align: center;
}
[class*="col-"] {
  padding: 0;
}

＆＃13;
