【中文标题】使用 CSS Grid 每隔一行着色【英文标题】:Coloring every other row using CSS Grid 【发布时间】:2020-02-03 16:30:10 【问题描述】:

我想为我正在使用 CSS Grid 构建的表格中的每一行着色。我无法让它工作,我只能让其他每一列都有颜色。这是我想要做的图片。会有更好的方法来构建它吗?我只使用 CSS Grid 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-rows: repeat(18, 35px);
  grid-column-gap: 0px;
  grid-row-gap: 0px;

【问题讨论】:

老实说对于一个表格来说,使用表格元素是最好的选择。然后,您可以使用tr:nth-child(even)(或奇数)来设置行的样式。如果您想学习网格,请构建网格布局,而不是表格。类似于侧边栏,画廊中的图像网格。 【参考方案1】:

如果您有一个六列网格,那么每 6+1 个元素就有一个新行,对于每个奇数行上的替代模式,那么您的重复模式每 12+1 个元素开始。 :nth-child(n+n) 将在这里为您提供帮助:

.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)

注意:如果您的任何元素跨越超过 1 个单元格:nth-child(n+x) 规则将中断

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

:nth-child()

:nth-child() CSS 伪类根据元素在一组兄弟元素中的位置匹配元素。

【讨论】:

:nth-child(n+n) 上的信息链接(即使看起来很明显)会有所帮助。很难搜索这样的东西,因为我们没有提供该技术的名称。 @BBaysinger 好点,添加了指向 mdn 的链接以供参考。【参考方案2】:

您正在为每一行定义一个固定的高度,以便您可以轻松地考虑重复渐变:

这行得通,但是如何,重复线性梯度在做什么?还有差距会打破这张桌子吗?而且您也不能在子项上为自己辩护,因为它们也会破坏表格。
