title: Koala Sass - Why autoprefix not work?
body: <p>I use Koala App for Sass compilation.</p>
  
  <p>I want to make the automatic addition of prefixes for properties CSS3</p>
  
  <p><a href="http://i.stack.imgur.com/P6e2t.jpg" rel="nofollow">Screenshot my options</a></p>
  
  <p><strong>SCSS:</strong></p>
  
  <pre><code>$radius: 14px;
  
  .test {
      border-radius: $radius;
  }
  </code></pre>
  
  <p><strong>Result CSS (Compile WITH set option "Autoprefix"):</strong></p>
  
  <pre><code>.test {
    border-radius: 14px;
  }
  </code></pre>
  
  <p><strong>Result CSS (Compile WITHOUT set option "Autoprefix"):</strong></p>
  
  <pre><code>.test {
    border-radius: 14px;
  }
  </code></pre>
  
  <p>The same result. Why autoprefix not work?</p>
  
  <p><strong>That's what I want to get after compilation</strong></p>
  
  <pre><code>.test {
    -webkit-border-radius: 14px;
    -moz-border-radius: 14px;
    border-radius: 14px;
  }
  </code></pre>
