Lists are powerful tools for grouping similar elements, and lists give visitors to your site an easy way to zoom in on groups of information. Just about anything fits in a list, from sets of instructions to collections of links. Definition lists group terms and definitions into a single list and require three elements to complete the list:
  • : Holds the list definitions (dl = definition list)

  • : Defines a term in the list (dt = definition term)

  • : Defines a definition for a term (dd = definition list definition)

        <title>Definition Lists</title>
        <h1>Markup Language Definitions</h1>
            <dd>The Standard Generalized Markup Language</dd>
             <dd>The Hypertext Markup Language</dd>
             <dd>The markup language you use to create web pages.</dd>
            <dd>The Extensible Markup Language</dd>
