HTML 5 <dt> Tag

The HTML <dt> tag is used for specifying a definition term in a definition list.

A definition list is similar to other lists but in a definition list, each list item contains two or more entries; a term (dt) and a description (dd).

Note that a definition term can be linked to more than one description. There can also be multiple terms for a single description (for example, in the case where there are multiple spellings of a term being defined). In this case, each term must be enclosed in its own set of dt tags (there shouldn't be any more than one term within a single dt element).

Also note that the dt does not indicate that its contents are a term being defined, but this can be indicated using the dfn element.

Example

Here are two examples of <dt> usage.

• Example 1: Contains a list of terms and their definitions. Note the use of dfn to indicate that this is the defining instance of the term.
• Example 2: Here, a term is linked to three values.

Attributes

HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The attributes that you can add to this tag are listed below.
