  <style>
  input
    {
      font-size: 300%;
    }

  input::grammar-error
    {
      color: maroon;
      text-decoration: underline dotted red;
    }
  </style>

  <p>PREREQUISITE: User agent needs to have an enabled and capable grammar error module. If it does not, then this test does not apply to such user agent.

  <p>Test passes if each glyph of "thing" is maroon and if "thing" is underlined with a red dotted line.

  <div><input type="text" value="Many thing can happen"></div>
