The <dt> tag is used to code a description term in a description list, leading into one or more detail description elements. Note that in previous versions of HTML this element was called definition term, but since the purpose of the HTML 5 <dfn> tag is to code a definition, the <dt> tag by itself does not identify a term being defined. To define a list of terms, such as for a glossary, each term defined should be identified by putting it inside a dfn element as shown in this example:

This is an actual working example of the <dt> 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.
