title: Remove input date placeholder including slash
body: <p>I know there is other similar question to this out there. But none of them show how to remove all the placeholder on the input date, only the letters 'dd', 'mm' and 'yyyy'.</p>
  
  <p>I already tried to use this:</p>
  
  <pre><code>::-webkit-datetime-edit-year-field:not([aria-valuenow]),
  ::-webkit-datetime-edit-month-field:not([aria-valuenow]),
  ::-webkit-datetime-edit-day-field:not([aria-valuenow]) {
    color: transparent;
  }
  </code></pre>
  
  <p>But like i said, the bars are still there, see this fiddle: <a href="https://jsfiddle.net/egj83yq4/" rel="nofollow">https://jsfiddle.net/egj83yq4/</a></p>
