Definition list

Definition lists vary only slightly from other types of lists in that list items consist of two parts: a term and a description. The term is given by the DT element and is restricted to inline content. The description is given with a DD element that contains block-level content. [Source: W3C]

Definition list w/ multiple paragraphs

The style sheet provided with this plugin will render these paragraphs…

… to the left of the term being defined.

Definition list w/ multiple “paragraphs”

Another way to separate blocks of text in a definition…

… is to simply have multiple definitions for a term (or group of terms).

This definition list has DD tags without any preceding DT tags.

Hey, it's legal XHTML.

Just like DT tags without following DD tags.

? But DT tags can't contain paragraphs. That would not be legal XHTML. .. If you try, the result will be rendered oddly.
