title: Make HTML form input hints that pops up with JavaScript accessible?
body: <p>Imagine I have a form with a hidden tip:</p>
  
  <pre><code>&lt;form&gt;
      &lt;input type='text' id='name' placeholder='Name'&gt;
      &lt;span id="name_hint" style="display: none;"&gt;Please enter your name&lt;/span&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>And jQuery pops up the tip when input value is invalid:</p>
  
  <pre><code>$('#name').on('blur', function(){
      if(!this.value.length) {
          $('#name_hint').show();
      }
  });
  </code></pre>
  
  <p>When that user left the text input without entering anything how do I tell web reader to read content of hint that now visible hint?</p>
