  2. London
  3. Berlin
  4. Paris
<ol>
  <li>Amsterdam</li>
  <li>London</li>
  <li>Berlin</li>
  <li>Paris</li>
</ol>

li = list item

Using <ol>

The <ol> element creates an ordered list of items (numeric or alphabetical).

List items are added with <li> tags placed inside the <ol> element.

More Examples

A variety of <ol> elements, each with their own numbering.

  • The first is alphabetic.
  • The second is numeric, starting at 50, and
  • The third is with roman numbers in reverse order.
  1. Amsterdam
  2. London
  3. Berlin
  4. Paris
  1. Amsterdam
  2. London
  3. Berlin
  4. Paris
  1. Amsterdam
  2. London
  3. Berlin
  4. Paris
<ol type="a">
  <li>Amsterdam</li>
  <li>London</li>
  <li>Berlin</li>
  <li>Paris</li>
</ol>

<ol start="50">
  <li>Amsterdam</li>
  <li>London</li>
  <li>Berlin</li>
  <li>Paris</li>
</ol>

<ol type="I" reversed>
  <li>Amsterdam</li>
  <li>London</li>
  <li>Berlin</li>
  <li>Paris</li>
</ol>

Tip: The start attribute sets the starting value for the list. And reversed reverses the numbering.
