HTML 5 <dl> Tag

The HTML <dl> tag is used for declaring 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 defintion term (dt) does not indicate that its contents are a term being defined, but this can be indicated using the dfn element.


Here are two examples of <dl> usage.


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.

Element-Specific Attributes

The following table shows the attributes that are specific to this tag/element.


Global Attributes

The following attributes are standard across all HTML 5 tags.

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content Attributes

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

Here are the standard HTML 5 event handler content attributes.

For a full explanation of these attributes, see HTML 5 event handler content attributes.
