ol – ordered list


For technical reasons, the title of this article is not the text used to call this API. Instead, use ol


The ol element is used to define an ordered list. The element encloses one or more list items, enclosed in li elements.

Overview Table

DOM Interface
Permitted contents One of the following:
  • Either: Zero or more li elements.
  • Or: A template element.
  • Or: any combination of the above two
Permitted parents Any element that can contain [flow content](/w/index.php?title=html/concepts/flowContent&action=edit&redlink=1).
Tag omission A **ol** element must have both a start tag and an end tag.
The **ordered list**, represented by the **ol** element, is most often used to group a list of items, enclosed in [**li**](/html/elements/li) elements, together in an ordered and semantic way.


This example uses the ol element to create a numbered list.

  <li>This is the first list item</li>
  <li>This is the second list item</li>

Typical browser default CSS properties for the ol element.
