title: Date format suggestion (dd-mm-yy) during typing in html input field
body: <p>The question is more to do with the user interface and experience. So I have a date input field in my JSP page. I want a semi-transparent <code>dd-mm-yyyy</code> to be present while entering the date.</p>
  
  <p>I currently have <code>dd-mm-yyyy</code> placeholder in place which comes up when the input field is in focus. But as soon as I type, the placeholder vanishes</p>
  
  <pre><code>&lt;body&gt;
  &lt;input type="tel" name="dobfield" id="dobfield" class="input_c" autocomplete="off" value='&lt;s:property value="dobfield" /&gt;'&gt;
  &lt;body&gt;
  </code></pre>
  
  <p>as of now, when I click on the field, I get <code>dd-mm-yyyy</code> as a placeholder. But as soon as I start typing the placeholder vanishes.</p>
  
  <p>This is the sequence of change that must happen while I type. Preferably, the <code>dd-mm-yyyy</code> must be semi-transparent or grey.</p>
  
  <pre><code>dd-mm-yyyy
  1d-mm-yyyy
  12-mm-yyyy
  12-1m-yyyy
  12-12-yyyy
  12-12-1yyy
