使用 css 计数器生成序数值？

Question

我猜这是不可能的，但想知道是否有人尝试使用 CSS Counters 生成序数（第 1、第 2、第 3 等）并取得成功？

显然这在 JavaScript 中是微不足道的，但希望找到一个仅样式解决方案。

Answer 1

像这样？

body {
  counter-reset: section;
}

h3::before {
  counter-increment: section;
  content: counter(section);
}

h3:nth-child(1)::before {
  content: counters(section, "") "st ";
}

h3:nth-child(2)::before {
  content: counters(section, "") "nd ";
}

h3:nth-child(3)::before {
  content: counters(section, "") "rd ";
}

h3:nth-child(n+4)::before {
  content: counters(section, "") "th ";
}
h3:nth-child(10n+1)::before {
  content: counters(section, "") "st "
}
h3:nth-child(10n+2)::before {
  content: counters(section, "") "nd "
}
h3:nth-child(10n+3)::before {
  content: counters(section, "") "rd "
}
h3:nth-child(11)::before {
  content: counters(section, "") "th "
}
h3:nth-child(12)::before {
  content: counters(section, "") "th "
}
h3:nth-child(13)::before {
  content: counters(section, "") "th "
}

Answer 2

如果您必须在每个数字上添加 th，这将很容易。但在这种情况下，您需要更改第 1、2、3、21、22、23、31、32 等...

所以你需要在这里使用第n个子概念。使用 :nth-child 定位元素。

您还需要使用 :not 选择器来不更改第 11、12、13 个元素

body {
  margin: 0;
  font: 13px Verdana;
}

ul {
  margin: 0;
  padding: 0;
  list-style: none;
  counter-reset: item;
}

ul li {
  margin-bottom: 5px;
  position: relative;
}

ul li:before {
  counter-increment: item;
  content: counter(item)"th. ";
  color: red;
  font-weight: bold;
}

ul li:nth-child(10n+1):not(:nth-child(11)):before {
  content: counter(item)"st. ";
}

ul li:nth-child(10n+2):not(:nth-child(12)):before {
  content: counter(item)"nd. ";
}

ul li:nth-child(10n+3):not(:nth-child(13)):before {
  content: counter(item)"rd. ";
}

<ul>
  <li>listItem</li>
  <li>listItem</li>
  <li>listItem</li>
  <li>listItem</li>
  <li>listItem</li>
  <li>listItem</li>
  <li>listItem</li>

</ul>
