title: Declaring all CSS background properties in one line — especially background-size
body: <p>So here's my code:</p>
  
  <pre><code>background: url(images/my-image.png) no-repeat center center / cover;
  </code></pre>
  
  <p>This works fine on Chrome and Firefox but not on Safari for some reason?</p>
  
  <p>I used to declare my <code>background-size</code> on it's own line but as I understand it it should be possible to declare all properties in one line using a forward slash?</p>
  
  <p>Any help would be much appreciated. Thanks.</p>
