Social Media Troubles

I have a client that loves the plum theme, however the social media icons in the top corner of it completely take a visitor off of her site, she wants it to open to another window. I know it’s a simple addon of target = “_blank” to it, but for the life of me, I can’t get it to work. Here’s the code from the theme’s social-fa.php file, can you please tell me exactly where and how it should go…

<?php
/*
** Template to Render Social Icons on Top Bar
*/
for ($i = 1; $i < 8; $i++) :
$social = esc_attr(get_theme_mod(‘plum_social_’.$i));
if ( ($social != ‘none’) && ($social != ”) ) : ?>
“><i class=”fa fa-<?php echo $social; ?>”></i>
<?php endif;
endfor; ?>
