垂直对齐和 CSS 网格关系

Question

垂直对齐和 CSS 网格如何协同工作？我有一个元素紧挨着需要在中间精确对齐的元素。见下文：

.alphabet {
  font-size: 80px;
  /*Below is not working...why?*/
  vertical-align: middle;
}

.letter-grid {
      display: flex;
}

.filter-item-grid {
    display: grid;
    display: -ms-grid;
    grid-template-columns: auto auto;
    justify-content: space-between;
    align-content: space-between;
}

.letter-grid__filter-item {
    display: grid;
    display: -ms-grid;
    grid-template-rows: repeat(3,auto);
    grid-auto-flow: column;
    margin-left: 24px;
}

<section class="letter-grid">
  <span class="alphabet">a</span>
    <div class="filter-item-grid">
      <div class="letter-grid__filter-item">
        <h3 class="letter-grid__filter-title">
          <a href="#">Example 1</a>
        </h3>
        <h3 class="letter-grid__filter-title">
          <a href="#">Example 2</a>
        </h3>
         <h3 class="letter-grid__filter-title">
          <a href="#">Example 3</a>
         </h3>
      </div>
    </div>
</section>

在示例中，我将 alphabet 设置为 vertical-align: middle; 以尝试将 A 字符对齐到三个列表项的中间。 I referred to the vertical align documentation 上面写着：

The vertical-align property can be used in two contexts:

To vertically align an inline element's box inside its containing line box. For example, it could be used to vertically position an img in a line of text...

因为我使用的是 <span> 标签，是因为我只能在内联元素容器中使用垂直对齐，而不是 <section>?

垂直对齐不是将中间的A字符与列表元素对齐的正确方式吗？

不，vertical-align 在没有行内行框时将不起作用。

在这种情况下，您已将 span 设为 flex-child，并有效地删除了 span 的 inline 性质。

我建议在 alphabet 跨度上使用 flexbox。

.alphabet {
  font-size: 80px;
  display: flex;
  align-items: center;
}

.letter-grid {
  display: flex;
}

.filter-item-grid {
  display: grid;
  display: -ms-grid;
  grid-template-columns: auto auto;
  justify-content: space-between;
  align-content: space-between;
}

.letter-grid__filter-item {
  display: grid;
  display: -ms-grid;
  grid-template-rows: repeat(3, auto);
  grid-auto-flow: column;
  margin-left: 24px;
}

section * {
  border: 1px solid lightgrey;
}

<section class="letter-grid">
  <span class="alphabet">a</span>
  <div class="filter-item-grid">
    <div class="letter-grid__filter-item">
      <h3 class="letter-grid__filter-title">
        <a href="#">Example 1</a>
      </h3>
      <h3 class="letter-grid__filter-title">
        <a href="#">Example 2</a>
      </h3>
      <h3 class="letter-grid__filter-title">
        <a href="#">Example 3</a>
      </h3>
    </div>
  </div>
</section>
