title: Shortcode Ultimate Wordpress Adding Image to tab
body: <p>I'm trying to put unique icons onto a custom tabs created using shortcode ultimate, but nothing seems to be working. It may be something obvious that I'm missing. I made three custom css classes that I've attached to each tab. In the css, each class has a unique icon image. Nothing appears in the tab (I don't want any text in the tab, just an icon).</p>
  
  <p>My shortcode: </p>
  
  <pre><code>    [su_tabs]
        [su_tab class="my-custom-tab-1" title=""]
           some content
        [/su_tab]
        [su_tab class="my-custom-tab-2" title=""]
           some content
        [/su_tab]
        [su_tab class="my-custom-tab-3" title=""]
           some content
        [/su_tab]
       [/su_tabs]
  </code></pre>
  
  <p>My CSS:</p>
  
  <pre><code>     .su-tabs.my-custom-tab-1 div.su-tabs-nav .su-tabs-current { background-image: url('http://livedemo00.template-help.com/wordpress_53881/wp-content/themes/theme53881/images/icon1.png') }
       .su-tabs.my-custom-tab-2 div.su-tabs-nav .su-tabs-current { background-image: url('http://livedemo00.template-help.com/wordpress_53881/wp-content/themes/theme53881/images/icon2.png') }
       .su-tabs.my-custom-tab-3 div.su-tabs-nav .su-tabs-current { background-image: url('http://livedemo00.template-help.com/wordpress_53881/wp-content/themes/theme53881/images/icon3.png') }
       .su-tabs.my-custom-tab-4 div.su-tabs-nav .su-tabs-current { background-image: url('http://livedemo00.template-help.com/wordpress_53881/wp-content/themes/theme53881/images/icon4.png') }
  </code></pre>
  
  <p>Any help is appreciated.</p>
