title: How can I add a red asterisk in a placeholder?
body: <p>The placeholder should show Enter a name* with a white text but the * red.
  I'm using Bootstrap 4 in Chrome. My HTML and CSS code are these:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.form-control::-webkit-input-placeholder::after {
      color: red;
      text-align: right;
      font-size: 50px;
      content: "*";
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;input type="text" placeholder="Your Name" class="form-control py-4" style="background: #273a71; color: white; border: 0;"&gt;</code></pre>
  </div>
  </div>
  </p>
