title: Background Image ::placeholder::before
body: <p>I want to put an icon to the placeholder of an input like:</p>
  <pre><code>.vue-input input {
      &amp;::placeholder::before{
          content: '';
          display: inline-block;
          height: .75rem;
          width: 1.5rem;
          margin-right: .5rem;
          background-image: url(~/assets/flag-ch.png);
          background-size: 100% 100%;
          background-position: center;
      }
  </code></pre>
  <p>Is it possible to do that?</p>
