[Theme: Enigma] social icon code target="_blank"

Hi,

In the header.php and footer.php I see this code;

<?php if($wl_theme_options[‘facebook_link’]!=”) { ?>
<li class=”facebook” data-toggle=”tooltip” data-placement=”top” title=”Facebook”>“><i class=”fa fa-facebook”></i>

But where can I but the code, target=”_blank” so that when you click on the facbook icon opens a new window?

Thanks
