ARIA: aria-current attribute
A non-null aria-current state on an element indicates that this element represents the current item within a container or set of related elements.
Description
When you have a group of related elements, such as several links in a breadcrumb or steps in a multi-step flow, with one element in the group styled differently from the others to indicate to the sighted user that this is the current element within its group, the aria-current should be used to inform the assistive technology user what has been indicated via styling.
In a breadcrumb list, when a link within a set of pagination links is styled to indicate the user is currently on that page, aria-current="page" should be set on that link. In a multi step based process with a step indicator such as a multi-page survey or a multi step checkout or registration process, when the current step icon is visually different to represent that it is the current step, that icon's container should have aria-current="step" for assistive technology users who may not be able to "see" the visual difference.
The aria-current attribute indicates the element on which it is set, to a value other than false, represents the current item within a container or set of related elements. Only mark one element in a set of elements as current with aria-current.
The aria-current attribute accepts a limited list of values including page, step, location, date, time, true, and false. Any non-null string value not included in this list of enumerated values is treated as if aria-current="true" were set, not the default false value. If the attribute is not present, is an empty string, is present with no value, or is set to aria-current="false" it is not exposed to the user.
When something is selected rather than current, such as a tab in a tablist, use aria-selected to indicate the currently-displayed tabpanel.
Note:
Don't use aria-current as a substitute for aria-selected in gridcell, option, row or tab.
Example
The breadcrumb for the "current page" should have aria-current="page" set on it.
<nav aria-label="Breadcrumb" class="breadcrumb">
  <ol>
    <li>
      <a href="../../../../../">Web technology for developers</a>
    </li>
    <li>
      <a href="../../../../">Accessibility</a>
    </li>
    <li>
      <a href="../../../">ARIA</a>
    </li>
    <li>
      <a href="../../">ARIA States and Properties</a>
    </li>
    <li>
      <a href="./" aria-current="page">ARIA: `aria-current` attribute</a>
    </li>
  </ol>
</nav>
If the element representing the current page in the breadcrumb was not a link, the aria-current is optional.
