Definition list
<dl>, dl, <dt>, <dd>, description list, dt dd, key-value listDefinition
The HTML list of name–value groups — <dl> holding pairs of <dt> (the term, or name) and <dd> (the description, or value) — for a glossary, a spec sheet, metadata, a FAQ, or any list where each item is a label and its content; renamed the description list in HTML5 because the pairs need not be definitions
The element for anything that is a table with two columns and no header row: the about page’s three sections are one (<dt> What this is, <dd> the paragraph), a resource’s publisher-date-format block would be one, a component’s props table is arguably one. Several <dt>s may share a <dd> and vice versa; a <div> may wrap each pair for styling since HTML5. The field-label and eyebrow voices on this site were made for the <dt>. Screen readers announce the pairs, which a two-column grid of <div>s cannot promise.
Names and their values, in pairs. When the left column is a label and the right one is what it labels, this is the element, and a table with no header row is the tell that it should have been.
