title: parallax image not working in safari
body: <p>Here is my code for parallax image</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>body,html{
  height:100%;
  }
  
  .booking {
      margin-top: 60px;
  
      background-image: url(http://via.placeholder.com/1000x800);
      background-attachment: fixed;
      background-position: center;
      background-repeat: no-repeat;
      background-size: cover;
      padding-top: 50px;
      padding-bottom: 50px;
  }
  
  .gray1 {
      background: #252525;
  }
  
  .opacity-fl1 {
      position: absolute;
      width: 100%;
      opacity: 0.8;
      padding-bottom: 244px;
  
      padding-top: -200px;
      margin-top: -50px;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;section class="booking"&gt;
   &lt;div class="opacity-fl1 gray1"&gt;&lt;/div&gt;
  &lt;h1&gt;Hello world&lt;/h1&gt;
  
  &lt;/section&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>It is working fine in all browsers except safari (In safari only  background: #252525 is showing). Can someone please explain me what is wrong here?</p>
  
  <p>Thank You.</p>
