Technique ARIA26:Using aria-current to identify the current item in a set
About this Technique
This technique relates to:
- 1.3.1 Info and Relationships (Sufficient when used for making information and relationships conveyed through presentation programmatically determinable)
- 2.4.8 Location (Sufficient)
This technique applies to technologies that support Accessible Rich Internet Applications (WAI-ARIA).
Description
The purpose of this technique is to programmatically indicate the current item in a user interface component that contains a set of related items. The aria-current attribute provides a way to programmatically indicate the element that is usually only visually highlighted, for example: the current page in a navigation bar.
Examples
Example 2: Identify the current step in a process
This is an example of aria-current used to mark up the steps in a recipe. It uses the attribute's step value to programmatically identify the current step:
<h2>Meringue Recipe Steps</h2>
<ol>
<li><a href="#oven">Heat your oven</a></li>
<li><a aria-current="step" href="#separate">Separate eggs</a></li>
<li><a href="#whisk-eggs">Whisk egg whites</a></li>
<li><a href="#whisk-sugar">Whisk in the sugar</a></li>
<li><a href="#pipe">Pipe mixture into shapes</a></li>
<li><a href="#bake">Bake</a></li>
<li><a href="#cool">Allow to cool</a></li>
</ol>
A working example of identifying the current step in a process.
Example 3: Identify the current time in a timetable
This is an example of aria-current used to mark up the current time in a timetable. It uses the attribute's time value to programmatically identify the current lesson in a class schedule:
<h2>Morning Class Schedule</h2>
<table>
<tr>
<th>Time</th>
<th>Subject</th>
</tr>
<tr>
<td>
<time datetime="2021-03-25T08:30">8:30-9:00am</time>
</td>
<td>Morning Meeting</td>
</tr>
<tr>
<td>
<time datetime="2021-03-25T09:00">9:00-9:30am</time>
</td>
<td>Math</td>
</tr>
<tr>
<td>
<time aria-current="time" datetime="2021-03-25T09:30">9:30-10:30am</time>
</td>
<td>Reading</td>
</tr>
<tr>
<td>
<time datetime="2021-03-25T10:30">10:30-10:45am</time>
</td>
<td>Recess</td>
</tr>
<tr>
<td>
<time datetime="2021-03-25T10:45">10:45-11:30am</time>
</td>
<td>Music</td>
</tr>
<tr>
<td>
<time datetime="2021-03-25T11:30">11:30-12:00pm</time>
</td>
<td>Independent Work</td>
</tr>
<tr>
<td>
<time datetime="2021-03-25T12:00">12:00-12:45pm</time>
</td>
<td>Lunchtime</td>
</tr>
