ARIA：定义角色

definition ARIA 角色指示元素是术语或概念的定义。

描述

definition ARIA 角色可以包含在作为术语或概念定义的元素上，类似于本机 <dfn> 元素。要将定义与正在定义的term关联，并提供可访问的名称，请使用role="term"引用正在定义的术语，并使用 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>，请使用 <dfn> 元素。如果可用，请始终使用本机元素。

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.
