Accessibility - hard to click the "do you want a backup" form

[edent]

Current HTML is:

<span id="success-message">
   Do you want a backup? 
   <form>
      <input type="radio" name="create_backup" value="true">Yes<br>
      <input type="radio" name="create_backup" value="false" checked="">No
   </form>
</span>

The "Yes" and "No" cannot be clicked - only the small radio buttons.

As per https://www.w3.org/WAI/tutorials/forms/labels/ the easiest solution is to wrap them in a label element.

<label>
   <input type="radio" name="create_backup" value="true">Yes
</label>
<br>
<label>
      <input type="radio" name="create_backup" value="false" checked="">No
</label>
