html - CSS网格列周围的框阴影

Question

我目前有一个具有动态行数的 CSS 网格，其中有应组合在一起的行子集。我想用投影将这些组的第一列包裹起来，但我不知道该怎么做。我可以用边框完成我想要的，因为我可以去掉中间元素的顶部和底部边框。

有没有办法在有或没有网格布局的情况下做到这一点？

.grid {
  display: grid;
  grid-template-columns: 250px 250px 250px;
  grid-column-gap: 20px;
}

.top,
.middle,
.bottom {
  border: 2px solid black;
}

.top {
  border-bottom: none;
}

.middle {
  border-top: none;
  border-bottom: none;
}

.bottom {
  border-top: none;
}

.title {
  text-align: center;
  
  padding: 5px 20px;
}

.title span {
  margin: 0 20px;
}

.title,
.details,
.actions {
  text-align: center;
  vertical-align: middle;
  margin: auto 0;
}

<div class="grid">
  <span class="top title">
    <span>row 1 title</span>
  </span>
  <span class="details">row 1 details</span>
  <span class="actions">row 1 actions</span>
    
  <span class="middle title">
    <span>row 2 title</span>
  </span>
  <span class="details">row 2 details</span>
  <span class="actions">row 2 actions</span>
    
  <span class="middle title">
    <span>row 3 has an extra long tile that wraps around</span>
  </span>
  <div class="details">row 3 details</div>
  <span class="actions">row 3 actions</span>
    
  <span class="bottom title">
    <span>row 4 title</span>
  </span>
  <span class="details">row 4 details</span>
  <span class="actions">row 4 actions</span>
  
  <span class="top title">
    <span>row 5 title</span>
  </span>
  <span class="details">row 5 details</span>
  <span class="actions">row 5 actions</span>
  
  <span class="bottom title">
    <span>row 6 title</span>
  </span>
  <span class="details">row 6 details</span>
  <span class="actions">row 6 actions</span>
</div>

无法将样式应用于特定列或行中的所有网格项，也无法为此对它们进行分组。您已经在做直接定位元素的可能选项。

黑客解决方案

在这里，我将使用您正在使用 top、middle 和 bottom 类以及 盒子阴影:

• 使用一个方便 box-shadow 将一个伪元素放在网格项后面第一列，

• 在 grid item 上使用 background 来匹配列，从而隐藏行与行之间的阴影，

• 现在使用 margin 分隔 bottom 类。

.grid {
  display: grid;
  grid-template-columns: 250px 250px 250px;
  grid-column-gap: 20px;
}

.top:after,
.middle:after,
.bottom:after {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: -1;
  box-shadow: 0 0px 10px 2px #ddd;
  background: #fff;
}

.title.bottom {
  margin-bottom: 15px;
  background: transparent;
}

.title {
  text-align: center;
  position: relative;
  padding: 5px 20px;
  background: #fff;
}

.title span {
  margin: 0 20px;
}

.title,
.details,
.actions {
  text-align: center;
  vertical-align: middle;
  margin: auto 0;
}

<div class="grid">
  <span class="top title">
    <span>row 1 title</span>
  </span>
  <span class="details">row 1 details</span>
  <span class="actions">row 1 actions</span>
    
  <span class="middle title">
    <span>row 2 title</span>
  </span>
  <span class="details">row 2 details</span>
  <span class="actions">row 2 actions</span>
    
  <span class="middle title">
    <span>row 3 has an extra long tile that wraps around</span>
  </span>
  <div class="details">row 3 details</div>
  <span class="actions">row 3 actions</span>
    
  <span class="bottom title">
    <span>row 4 title</span>
  </span>
  <span class="details">row 4 details</span>
  <span class="actions">row 4 actions</span>
  
  <span class="top title">
    <span>row 5 title</span>
  </span>
  <span class="details">row 5 details</span>
  <span class="actions">row 5 actions</span>
  
  <span class="bottom title">
    <span>row 6 title</span>
  </span>
  <span class="details">row 6 details</span>
  <span class="actions">row 6 actions</span>
</div>
