Hi
The icon code is not present in your code.
<ul class="social-list">
<li><a href="#" title="Facebook" class="facebook"><i class="fa fa-facebook" aria-hidden="true"></i></a></li>
<li><a href="#" title="Twitter" class="twitter"><i class="fa fa-twitter" aria-hidden="true"></i></a></li>
<li><a href="#" title="Instagram" class="instagram"><i class="fa fa-instagram" aria-hidden="true"></i></a></li>
<li><a href="#" title="Google plus" class="google-plus"><i class="fa fa-google" aria-hidden="true"></i></a></li>
</ul>
Kindly set the default Editor to None before editing the custom html module and add the code again.
