<p>Required fields are followed by <span aria-label="required">*</span>.</p>

<!-- So this: -->
<!--div>
  <label for="username">Name:</label>
  <input id="username" type="text" name="username" required>
  <label for="username"><span aria-label="required">*</label>
</div-->

<!-- would be better done like this: -->
<!--div>
  <label for="username">
    <span>Name:</span>
    <input id="username" type="text" name="username" required>
    <span aria-label="required">*</span>
  </label>
</div-->

<!-- But this is probably best: -->
<div>
  <label for="username">Name: <span aria-label="required">*</span></label>
  <input id="username" type="text" name="username" required />
</div>
