ARIA：定義角色

definition ARIA 角色指示元素是術語或概念的定義。

描述

definition ARIA 角色可以包含在作為術語或概念定義的元素上，類似於本機 <dfn> 元素。要將定義與正在定義的term關聯，並提供可訪問的名稱，請使用role="term"引用正在定義的術語，並使用 aria-labelledby。

html
<p>
  <span role="term">Mansplaining</span>,
  <span role="definition">
    a portmanteau of "man" and "explain", is the patronizing act of explaining
    without being asked to do so, to someone already learned on the topic, often
    after someone has already explained it
  </span>.
</p>

注意： 而不是使用具有 term 和 definition 角色的<span>，請使用 <dfn> 元素。如果可用，請始終使用本機元素。

html
<p>
  <dfn>Mansplaining</dfn>, a portmanteau of "man" and "explain", is the
  patronizing act of explaining without being asked to do so, to someone already
  learned on the topic, often after someone has already explained it.
