Html ordered list 1.1, 1.2 (Nested counters and sc

问题:

I use nested counters and scope to create an ordered list:

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>

I expect the following outcome:

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

Instead, this is what I see (wrong numbering):

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

I have no clue, does anyone see where it goes wrong?

Uncheck "normalize CSS" - http://jsfiddle.net/qGCUk/3/ The CSS reset used in that defaults all list margins and paddings to 0

UPDATE http://jsfiddle.net/qGCUk/4/ - you have to include your sub-lists in your 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>

Use this style to change only the 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;
}

What shows up for me (under Chrome and Mac OS X)

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

How I did it

---

Instead of :

<li>Item 1</li>
<li>Item 2</li>
   <ol>
        <li>Subitem 1</li>
        <li>Subitem 2</li>
   </ol>

Do :

<li>Item 1</li>
<li>Item 2
   <ol>
        <li>Subitem 1</li>
        <li>Subitem 2</li>
   </ol>
</li>

This is a great solution! With a few additional CSS rules you can format it just like an MS Word outline list with a hanging first line indent:

OL { 
  counter-reset: item; 
}
LI { 
  display: block; 
}
LI:before { 
  content: counters(item, ".") "."; 
  counter-increment: item; 
  padding-right:10px; 
  margin-left:-20px;
}

I encountered similar problem recently. The fix is to set the display property of the li items in the ordered list to list-item, and not display block, and ensure that the display property of ol is not list-item. i.e

li { display: list-item;}

With this, the html parser sees all li as the list item and assign the appropriate value to it, and sees the ol, as an inline-block or block element based on your settings, and doesn't try to assign any count value to it.
