实例

Odd 和 even 是可用于匹配下标是奇数或偶数的子元素的关键词(第一个子元素的下标是 1)。

在这里,我们为奇数和偶数 p 元素指定两种不同的背景色:

p:nth-of-type(odd) {
  background: red;
}

p:nth-of-type(even) {
  background: blue;
}

实例

使用公式 (an + b)。描述:表示周期的长度,n 是计数器(从 0 开始),b 是偏移值。

在这里,我们指定了下标是 3 的倍数的所有 p 元素的背景色:

p:nth-of-type(3n+0) {
  background: red;
}
