HTML命令列表1.1、1.2(嵌套计数器和作用域)不起作用

html

我使用嵌套计数器和范围创建有序列表:

ol {

    counter-reset: item;

    padding-left: 10px;

}

li {

    display: block

}

li:before {

    content: counters(item, ".") " ";

    counter-increment: item

}


<ol>

    <li>one</li>

    <li>two</li>

    <ol>

        <li>two.one</li>

        <li>two.two</li>

        <li>two.three</li>

    </ol>

    <li>three</li>

    <ol>

        <li>three.one</li>

        <li>three.two</li>

        <ol>

            <li>three.two.one</li>

            <li>three.two.two</li>

        </ol>

    </ol>

    <li>four</li>

</ol>

我期望得到以下结果:

1. one
2. two
  2.1. two.one
  2.2. two.two
  2.3. two.three
3. three
  3.1 three.one
  3.2 three.two
    3.2.1 three.two.one
    3.2.2 three.two.two
4. four

相反,这是我看到的 (编号错误)

1. one
2. two
  2.1. two.one
  2.2. two.two
  2.3. two.three
2.4 three <!-- this is where it goes wrong, when going back to the parent -->
  2.1 three.one
  2.2 three.two
    2.2.1 three.two.one
    2.2.2 three.two.two
2.3 four

我不知道,有没有人看到哪里出了问题?

这是一个JSFiddle:http :

取消选中“规范化CSS” 使用的CSS重置将所有列表边距和填充默认设置为0

您必须在主目录中包含子列表<li>

ol {

  counter-reset: item

}

li {

  display: block

}

li:before {

  content: counters(item, ".") " ";

  counter-increment: item

}


<ol>

  <li>one</li>

  <li>two

    <ol>

      <li>two.one</li>

      <li>two.two</li>

      <li>two.three</li>

    </ol>

  </li>

  <li>three

    <ol>

      <li>three.one</li>

      <li>three.two

        <ol>

          <li>three.two.one</li>

          <li>three.two.two</li>

        </ol>

      </li>

    </ol>

  </li>

  <li>four</li>

</ol>
