title: How to show .webp in Chrome and .jpg in Firefox or IE/Edge?
body: <p>Is there any working example to show <code>.webp</code> format file in Chrome and a different <code>.jpg</code> format file in Firefox and IE / Edge?</p>
  
  <p>I user now this <code>CSS</code> code:</p>
  
  <pre><code>#bgbox {
      background-imgage: url('../img/bg.webp');
  }
  </code></pre>
  
  <p>Is there a <code>-moz-background-image</code> or something like this?</p>
