sarriatur Hi
You can go to Editor - TinyMCE plugin manager => Use Joomla Text Filter, go to module manager, edit
"Social icons" module and add this code:
`<div>
<a href="https://plus.google.com/+gavickpro?rel=author" target="_blank" rel="noopener"><i class="gk-icon-gplus"></i></a>
<a href="https://twitter.com/gavickpro" target="_blank" rel="noopener"><i class="gk-icon-twitter"></i></a>
<a href="https://www.facebook.com/gavickpro" target="_blank" rel="noopener"><i class="gk-icon-fb"></i></a>
<a href="http://www.gavick.com/magazine/?format=feed&type=rss" target="_blank" rel="noopener"><i class="gk-icon-rss"></i></a>
</div>`
Hope it helps.
