The <dd> detail description tag is used to code the description of an item inside a dl element for a description list. Note that in previous versions of HTML these were called definition description and definition list respectively. However, since the purpose of the HTML <dfn> tag is to code a definition, the <dd> tag in HTML 5 by itself does not identify the definition of a term.

When displayed with its normal style, the flow content of the dd element is indented under the phrasing content of the dt element for the description term (formerly definition term) before it:

This is an actual working example of the <dd> tag example code below. In most HTML 5 browsers such as Firefox and Opera, the text inside the dfn element will be in an italic font, except for WebKit browsers such as Chrome and Safari which display it in an upright font.
