<h1><code><input></code> with <code>required</code> and "(Required)" added to label text</h1>
<p>← <a href="index.html">Return to main list</a></p>
<p>This is a test case designed to determine how a visual "required" indicator is announced by various screen readers.</p>
<h2>Note on <code>required</code> usage</h2>
<p>If the <code>required</code> attribute is applied, the invalid state is also set in accessibility APIs. So, form controls with <code>required</code> applied are announced as "Invalid entry" or "Invalid data", even before users have interacted with the control. <a href="https://github.com/w3c/aria/issues/1488" target="_blank">More details on the issue</a>.</p>
<p>Even though native HTML attributes should be used where possible, authors could choose to use <code>aria-required="true"</code> instead. However, authors should not use <code>aria-invalid="false"</code> to solve this issue.</p>
<blockquote>
<p><i>However, if the user has not attempted to submit the form, authors SHOULD NOT set the aria-invalid attribute on required widgets simply because the user has not yet entered data.</i></p>
