Creating table of contents in html

Question

Is it possible to create an ordered list like the following? I like this for a table of contents I\'m creating.

1. Into
2. Section1
   2.1 SubSection1
   2.

Answer 1

There's quite a number of jQuery plugins to generate a table of contents.

• Look at this one for starters

• Another one here, with ordered lists

Answer 2

This can indeed be done with pure CSS:

ol {
    counter-reset: item
}
li {
    display: block
}
li:before {
    content: counters(item, ".")" ";
    counter-increment: item
}

Answer 3

Have you seen this post: Number nested ordered lists in HTML

I don't think it can be done without using JS.

Answer 4

This code leads to the desired output for me:

<ol>
  <li>
    <a href="#Lnk">foo</a>
  </li>
  <li>
    <a href="#Lnk">bar</a>
    <ol>
      <li>
        <a href="#Lnk">baz</a>
      </li>
      <li>
        <a href="#Lnk">qux</a>
      </li>
    </ol>
  </li>
  <li>
    <a href="#Lnk">alpha</a>
    <ol>
      <li>
        <a href="#Lnk">beta</a>
      </li>
      <li>
        <a href="#Lnk">gamma</a>
      </li>
    </ol>
  </li>
</ol>

CSS:

ol {
    counter-reset: item;
}
li {
    display: block;
}
li::before {
    content: counters(item, ".")". ";
    counter-increment: item;
}
