title: blur without background image
body: <p>I creating theme (for me) for Cinnamon and i want to get blur effect on cinnamon panel, but i don't know how to do that. I know how to get blur on this:</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>.moreblur {
      position: fixed;
    left: 0;
    right: 0;
    z-index: 1;
  
    display: block;
    background-image: url(http://www.yosemitehikes.com/images/wallpaper/yosemitehikes.com-valley-winter-1366x768.jpg);
    width: 1200px;
    height: 800px;
  
    -webkit-filter: blur(10px);
    -moz-filter: blur(10px);
    -o-filter: blur(10px);
    -ms-filter: blur(10px);
    filter: blur(10px);
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="moreblur"&gt;&lt;/div&gt;  </code></pre>
  </div>
  </div>
  </p>
  
  <p>But remember: i need to get blur on background image, not myself image.
  Thanks.</p>
