I wanted to add houzz and another custom url via backend for a footer widget with shortcode.
But now I’m using code for adding it:
<ul class="social-icons large ">
<li class="houzz"><a target="_blank" href="#"><i class="fa-houzz"></i><i class="fa-houzz"></i></a></li>
<li class="facebook"><a target="_blank" href="#"><i class="fa-facebook"></i><i class="fa-facebook"></i></a></li>
<li class="twitter"><a target="_blank" href="#"><i class="fa-twitter"></i><i class="fa-twitter"></i></a></li>
<li class="youtube"><a target="_blank" href="#"><i class="fa-youtube"></i><i class="fa-youtube"></i></a></li>
<li class="pinterest"><a target="_blank" href="#"><i class="fa-pinterest"></i><i class="fa-pinterest"></i></a></li>
<li class="instagram"><a target="_blank" href="#"><i class="fa-instagram"></i><i class="fa-instagram"></i></a></li>
</ul>
