Question

使用CSS flexbox，如何在不使用css height属性的情况下，同时将所有div的内容垂直居中，同时在所有div上保持相同的高度？

Answer 1

HTML

<div class='outer'>
    <div class='inner'>A</div>
    <div class='inner'>B</div>
    <div class='inner'>C</div>
</div>

CSS

.outer {
    align-items: stretch;
    display: flex;
}

.inner {
    align-items: center;
    display: flex;
}

Answer 2

  .item-wrapper
    display: flex
    align-items: stretch
    justify-content: center

  .item
    width: 400px
    display: flex

Answer 3

使用Flexbox没有理由这样做。表/表格单元属性已经能够长时间执行此操作：

ul {
  display: table; /* optional */
}

li {
  display: table-cell;
  vertical-align: middle;
}

这就是Flexbox的样子：

ul {
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
}

li {
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  -webkit-box-orient: vertical;
  -moz-box-orient: vertical;
  -webkit-box-direction: normal;
  -moz-box-direction: normal;
  -webkit-flex-direction: column;
  -ms-flex-direction: column;
  flex-direction: column;
  -webkit-box-align: center;
  -moz-box-align: center;
  -ms-flex-align: center;
  -webkit-align-items: center;
  align-items: center;
  -webkit-box-pack: center;
  -moz-box-pack: center;
  -ms-flex-pack: center;
  -webkit-justify-content: center;
  justify-content: center;
}

如果您在孩子上设置 flex: 1，它将伸展以填充空间。

然后您可以在子容器上align-items: center。

.container {
  display: flex;
}

.item {
  flex: 1;
  display: flex;
  align-items: center;
  width: 200px;
  background-color: cadetblue;
  color: white;
  padding: 1rem;
  margin: 1rem;
}

.content {
  padding: 1rem;
  border: 2px solid lightcoral;
}

    <div class="container">
        <div class="item">
            <div class="content">
                Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do
                eiusmod tempor incididunt ut labore et dolore magna aliqua.
                Pulvinar neque laoreet suspendisse interdum consectetur libero.
                Diam sit amet nisl suscipit adipiscing bibendum est.
            </div>
        </div>
        <div class="item">
            <div class="content">
                Duis tristique sollicitudin nibh sit amet. Platea dictumst
                vestibulum rhoncus est pellentesque.
            </div>
        </div>
        <div class="item">
            <div class="content">
                Aliquam vestibulum morbi blandit cursus
            </div>
        </div>
    </div>
