Add social media

Bonjour,

I’d like to add a social media not initially plan in the theme, please does anybody know how to do?

I found in “header.php” a part in the code that might help partly, corresponding to the “sidebar-top” where the icons are set, but I don’t see how to finalise the personalisation or where adding the new icon.. (simple social icons also seems not wanting personalization.. in spite of my settings, it doesn’t want to change color or size of icons)

I had this part in header.php:

(if ( get_theme_mod( ‘icon9_link’ ) ) { ?>
” target=”_blank”>
<i class=”fa fa-viadeo-square fa-2x”></i>

<?php }

Thanks for helping!
