title: Unslider carousel "animation: 'fade'"
body: <p>I'm trying to make a carousel with <a href="http://unslider.com" rel="nofollow">http://unslider.com</a> like this:</p>
  
  <pre><code>$('.carousel').unslider({
    autoplay: true,
    speed: 750,
    delay: 3000,
    nav: false,
    infinite: true,
    arrows: {
      prev: '&lt;div class="prev-btn"&gt;&lt;/div&gt;',
      next: '&lt;div class="next-btn"&gt;&lt;/div&gt;'
    }
  })
  </code></pre>
  
  <p>All slides became invisible when i added the option <code>animation: 'fade'</code>. I cannot figure out why.</p>
