垂直对齐并排div中的内容

Question

我有两个div并排，其中一个（右）的内容比另一个（左）更多。我一直试图找到合适的一个，垂直对齐，所以它位于左侧中间位置。

以下是CodePen：https://codepen.io/anon/pen/OjyZNP?editors=1100

尝试在桌面上实现类似的功能：

＆＃13;

＆＃13;

.vertical-align {
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: row;
}

.bg-overlay {
  /*background: linear-gradient( rgba(140,113,94, .9), rgba(140,113,94, .1));*/
  background: linear-gradient(rgba(20, 20, 20, .7), rgba(20, 20, 20, .7));
  position: relative;
  display: table;
}

.owl-bg {
  background: url('https://www.smashingmagazine.com/wp-content/uploads/2015/06/10-dithering-opt.jpg');
  position: relative;
  z-index: -1;
  background-repeat: no-repeat;
  background-size: cover;
  background-position: center center;
  color: white;
}

.owl-ttl {
  display: inline-block;
  height: 100%;
}

.owl-ttl-text {
  position: relative;
  z-index: 100;
  color: white;
  display: initial;
  overflow: auto;
  min-height: inherit;
}

.owl-content-text {
  position: relative;
  z-index: 100;
  color: white;
  display: initial;
  overflow: auto;
  min-height: inherit;
  padding: 4vh;
  font-weight: 200;
  padding-left: 6vw;
}

.owl-bg:after {
  clear: both;
}

＆＃13;

              Owls are birds from the order Strigiformes, which includes about 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for
              silent flight. Exceptions include the diurnal northern hawk- owl and the gregarious burrowing owl.
              <br /> Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except Antarctica and some remote islands.
              <br /> Owls are divided into two families: the Strigidae family of true (or typical) owls; and the Tytonidae family of barn-owls.

Answer 1

为display: flex添加align-items: center和.pecan-text。演示：

＆＃13;

＆＃13;

.pecan-text {
  display: flex; /* new */
  align-items: center; /* new */
}

.vertical-align {
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: row;
}

.bg-overlay {
  /*background: linear-gradient( rgba(140,113,94, .9), rgba(140,113,94, .1));*/
  background: linear-gradient(rgba(20, 20, 20, .7), rgba(20, 20, 20, .7));
  position: relative;
  display: table;
}

.owl-bg {
  background: url('https://www.smashingmagazine.com/wp-content/uploads/2015/06/10-dithering-opt.jpg');
  position: relative;
  z-index: -1;
  background-repeat: no-repeat;
  background-size: cover;
  background-position: center center;
  color: white;
}

.owl-ttl {
  display: inline-block;
  height: 100%;
}

.owl-ttl-text {
  position: relative;
  z-index: 100;
  color: white;
  display: initial;
  overflow: auto;
  min-height: inherit;
}

.owl-content-text {
  position: relative;
  z-index: 100;
  color: white;
  display: initial;
  overflow: auto;
  min-height: inherit;
  padding: 4vh;
  font-weight: 200;
  padding-left: 6vw;
}

.owl-bg:after {
  clear: both;
}
