Summary

The dl element is used to define a description list. The element encloses one or more description terms, enclosed in dt elements, and description definitions (definitions of the terms), enclosed within dd elements.

Overview Table

DOM Interface: HTMLDListElement

Permitted contents One of the following:

Either: Zero or more groups each consisting of one or more dt elements followed by one or more dd elements.
Or: A template element.
Or: A template element or a dt element, followed by zero or more template, dt, and dd elements, followed by a template element or a dd element.

Permitted parents Any element that can contain [flow content](/w/index.php?title=html/concepts/flowContent&action=edit&redlink=1). Tag omission A **dl** element must have both a start tag and an end tag.

The **dl** element is often useful to create a semantic list of terms and their definitions, whether these are name value pairs, glossary terms and definitions, or anything other items that fit this pattern. **Description lists** allow you to do this easily inside HTML.

A description list is always wrapped by a single dl element. Inside that element you can place any number of child description topics, inside dt elements, and description definitions — the description or definition of the specified terms or topics — inside dd elements.

It doesn’t make sense to have an item without a description, or the other way round, but note that it is acceptable to have a single item with multiple descriptions, or a description with multiple items (see code examples section.)

The topics should always be placed before the descriptions.

A description list is not used as commonly as other types of list, except in journals, research papers, and other documentation where item/value pairs need to be displayed. For other uses, they are often not used as they are considered more difficult to style than other list types.

Examples

This example shows a simple definition list with two item/description pairs.

<dl>
  <dt>Coffee</dt>
  <dd>A popular hot drink.</dd>
  <dt>Coca Cola</dt>
  <dd>One of the leading brands of a popular cold fizzy drink.</dd>
</dl>
