HTML nested counters and scopes cause ordered lists 1.1, 1.2 not to work properly

Question

我使用嵌套计数器和作用域来创建有序列表：

<code>ol {
    counter-reset: item;
    padding-left: 10px;
}
li {
    display: block
}
li:before {
    content: counters(item, ".") " ";
    counter-increment: item
}</code>

<code><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></code>

我期望的结果如下：

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

但实际上，我看到的是（错误的编号）：

<code>1. one
2. two
  2.1. two.one
  2.2. two.two
  2.3. two.three
2.4 three <!-- 这是出错的地方，当返回到父级时 -->
  2.1 three.one
  2.2 three.two
    2.2.1 three.two.one
    2.2.2 three.two.two
2.3 four
</code>

我不知道，有人看出哪里出错了吗？

Answer 1

Use this style to only change nested lists:

ol {
    counter-reset: item;
}

ol > li {
    counter-increment: item;
}

ol ol > li {
    display: block;
}

ol ol > li:before {
    content: counters(item, ".") ". ";
    margin-left: -20px;
}

Answer 2

Uncheck "Standardize CSS" - http://jsfiddle.net/qGCUk/3/ The CSS reset used in this sets the margins and padding of all lists to 0

UPDATE http://jsfiddle.net/qGCUk/4/ - You must include your sublist in the main <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>
