css - 使用 CSS Grid 每隔一行着色

Question

我想为我使用 CSS 网格构建的表格中的每一行着色。虽然我无法让它工作，但我只能让所有其他列着色。这是我想要做的事情的图片。会有更好的方法来构建它吗？我使用 CSS Grid 只是因为它是我想学习的新东西。

这是我当前的代码:

  .wrapper {
  border-style: solid;
  border-color: rgb(230, 230, 230);
  font-weight: bold;
  text-align: center;
  display: grid;
  grid-template-columns: repeat(6, 1fr);
  grid-template-rows: repeat(18, 35px);
  grid-column-gap: 0px;
  grid-row-gap: 0px;
}

.wrapper>div:nth-child(odd) {
  background: #ddd;

<div class="container">

Answer 1

如果你有一个六列网格，那么你每 6+1 个元素就有一个新行，对于每个奇数行的替代模式，那么你的重复模式每 12+1 个元素开始。 :nth-child(n+n) 会在这里帮助你:

.wrapper {
  border-style: solid;
  border-color: rgb(230, 230, 230);
  font-weight: bold;
  text-align: center;
  display: grid;
  grid-template-columns: repeat(6, 1fr);
  grid-template-rows: repeat(18, 35px);
  grid-column-gap: 0px;
  grid-row-gap: 0px;
}
/* 6 columns, odd rows starts every 12th element, a row is made of six elements, so here is 6 selectors to select an entire row*/
.wrapper>div:nth-child(12n+1),
.wrapper>div:nth-child(12n+2),
.wrapper>div:nth-child(12n+3),
.wrapper>div:nth-child(12n+4),
.wrapper>div:nth-child(12n+5),
.wrapper>div:nth-child(12n+6)
{
  background: #ddd;
  }

注意:如果您的任何元素跨越超过 1 个单元格，:nth-child(n+x) 规则 会破裂。

https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-child#examples

:nth-child()

The :nth-child() CSS pseudo-class matches elements based on their position in a group of siblings.

如果网格有间隙，注释会显示一个可能的问题:

  border-style: solid;
  border-color: rgb(230, 230, 230);
