title: Frosted glass look
body: <p>Is there an alternative to backdrop-filter in CSS?
  To get this example working I have to enable <a href="http://chrome://flags/#enable-experimental-web-platform-features" rel="nofollow noreferrer">chrome://flags/#enable-experimental-web-platform-features</a></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 {
    background: url('http://verdewall.com/wp-content/uploads/2016/08/Background-Images-4H9.jpg') no-repeat center;
  }
  
  .glass {
    width: 100%;
    height: 500px;
    background: rgba(0,0,0,0.8);
    
    -webkit-backdrop-filter: contrast(4) blur(30px);
    backdrop-filter: contrast(4) blur(30px);
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
    &lt;meta charset="utf-8"&gt;
    &lt;meta name="viewport" content="width=device-width"&gt;
    &lt;title&gt;Blur&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;div class="glass"&gt;
    &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Here is what it looks like with the experimental features enabled:

  <p>The problem is the content below it will be dynamic. So not all of it will be images and the alternatives I find only work with images. Like the translucency with the blur shown here:
