Instagram icon in the footer

Hi!
I would like to add 3 icons in the footer (not in the socket): Mail, Instagram and LinkedIn.
I found the following code for mail and LinkedIn, that I placed in a text widget:
<ul class=”noLightbox social_bookmarks icon_count_2″><li class=”social_bookmarks_mail av-social-link-mail social_icon_1″>(Email address hidden if logged out) ?subject=Inquiry from WGM Website” title=”Mail”><span class=”avia_hidden_link_text”>Mail</span><li class=”social_bookmarks_linkedin av-social-link-linkedin social_icon_2″><span class=”avia_hidden_link_text”>Linkedin</span>

I also placed this code in the Quick CSS:
#footer .social_bookmarks li {
clear: none;
}

It works!
But I’m now missing the code for Instagram.
Can you please help?
Thanks!
