In order to code a definition list, we need to utilize three different sets of tags. First, the <dl> tag, allows us to specify that we are creating a definition list. When comparing with our previous lists, the <dl> tag replaces our <ol> or <ul> tag sets. Our second tag, the <dt> tag, specifies that we are prividing the definition term. Our third and final component is the <dd> tag which specifies that we are providing our definion.
