dt

A definition list term

Syntax

<dt></dt>

Attributes Core, I18n, Events, HTML5 Only: Global

Description

Use the dt element to denote a term in a definition list (dl). The term is described by at least one corresponding dd element that follows the dt. Please note that a dt may contain inline content only.

The simplest arrangement within a dl is one dt (term) grouped with one dd (description). Another possibility is shown in the following example, with one dt associated with multiple dds since director can be defined in many ways. The dl entry in this chapter elaborates on these and other configurations, definition lists in general, and the role of dt.

Example:

<dl>
   <dt><dfn>director</dfn></dt>
   <dd>One who directs</dd>
   <dd>One who oversees a group or an organization</dd>
   <dd>One who leads all aspects of the creation of a film</dd>
   . . .
</dl>

Most user agents typically render a definition list by default as shown here, except for the italics on director, which is because of the dfn element:

  • director
    • One who directs
    • One who oversees a group or an organization
    • One who leads all aspects of the creation of a film

TIP

You might be wondering why director is wrapped in a dfn element. Isn't the dt sufficient to indicate it's a term? It depends on the context. Yes, a dt does denote a term, but a dfn has a more specific meaning, and in the context of a dt, dfn indicates the list is defining terms like a dictionary or glossary does. Please see the dl entry in this chapter and the dfn entry in Chapter 5 for more information and examples.
