垂直对齐页面上的元素，同时保持相同的高度

Question

我试图让同一行中的每个元素都具有相同的高度。我不希望元素被拉伸。它们还应该在页面内垂直对齐。我设法使用 align-items:center; 使它们在页面上垂直对齐，但是，同一行中的框高度不同。知道我在这里做错了什么吗？我不想使用固定高度来实现这一点。 JS Bin

我正在努力实现这一目标；

非常感谢。

body {
  background: lightblue;
  padding: 1rem;
}

.help-boxes {
  flex-wrap: wrap;
  display: flex;
  align-items: center;
  justify-content: space-between;
  height: 100%;
}

.box-wrap {
  height: 92vh;
}

.help-box-link {
  background: #fff;
  -webkit-box-shadow: 0 1rem 3rem rgba(22, 28, 45, 0.175);
  box-shadow: 0 1rem 3rem rgba(22, 28, 45, 0.175);
  border-radius: 3px;
  margin-bottom: 2%;
  padding: 1rem;

也为子项使用 flex 并删除父项中的 align-items，改为在您的子项中使用它。

body {
  background: lightblue;
  padding: 1rem;
}

.help-boxes {
  display: flex;
  justify-content: space-around;
  flex-flow: column wrap;
  height: 100%;
}

.box-wrap {
  height: 92vh;
}

.help-box-link {
    background: #fff;
    -webkit-box-shadow: 0 1rem 3rem rgba(22, 28, 45, 0.175);
    box-shadow: 0 1rem 3rem
    rgba(22, 28, 45, 0.175);
    border-radius: 3px;
    margin: 2% 1em;
    padding: 1rem;
    flex: 1 0 31.33%;
    display: flex;
    align-items: center;
}

Answer 2

在 .help-boxes class 中进行此更改

align-items: stretch; // Alter this line of 'center' to 'stretch'

这样所有的框都将根据其中最大的框对齐。

Answer 3

通过使用网格。

body {
  background: lightblue;
  padding: 1rem;
}

.box-wrap{ 
  height: 94vh;
  align-items: center;
}

.help-boxes{
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-gap: 20px;
}

.help-box-link {
  display: block;
  background: #fff;
  box-shadow: 0 1rem 3rem rgba(22, 28, 45, 0.175);
  border-radius: 3px;
  margin-bottom: 2%;
  padding: 1rem;
  flex: 0 0 31.33%;
}

<div class="box-wrap">
  <div class="help-boxes">
    <a href="#" role="button" class="help-box-link">
      <p class="help-box__desc">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
