The example suggest there is a `.info` class available for labels. However there is no definition for `.info` class, the demo is simply rendering the default `.label`.
```html_example
<span class="label alert"><i class="fi-x-circle"></i> Alert Label</span>
<span class="label warning"><i class="fi-x"></i> Warning Label</span>
-<span class="label info"><i class="fi-widget"></i> Info Label</span>
+<span class="label"><i class="fi-widget"></i> Default Label</span>
```
