Hi osbert
For the sticky menu take a look at THIS DISCUSSION
Regarding social module you can add a custom.html module with this html
<ul class="social-list">
<li><a href="#" title="Facebook" class="facebook"><span class="fa fa-facebook" aria-hidden="true"></span><span class="element-invisible">empty</span></a></li>
<li><a href="#" title="Twitter" class="twitter"><span class="fa fa-twitter" aria-hidden="true"></span><span class="element-invisible">empty</span></a></li>
<li><a href="#" title="Instagram" class="instagram"><span class="fa fa-instagram" aria-hidden="true"></span><span class="element-invisible">empty</span></a></li>
<li><a href="#" title="Google plus" class="google-plus"><span class="fa fa-google" aria-hidden="true"></span><span class="element-invisible">empty</span></a></li>
</ul>
Add to your custom.css file this code for social-list
.social-list {
list-style: none;
padding: 0;
margin: 0;
}
.social-list li {
display: inline-block;
}
.social-list li a {
display: inline-block;
}
.social-list li .fa {
background: #ffffff;
border-radius: 10px;
color: #98d14c;
line-height: 24px;
height: 24px;
font-size: 13px;
text-align: center;
width: 24px;
}
.social-list.social-color li .fa {
color: #ffffff;
}
.social-list.social-color li .fa.fa-facebook {
background: #3b5999;
}
.social-list.social-color li .fa.fa-twitter {
background: #55acee;
}
.social-list.social-color li .fa.fa-instagram {
background: #e4405f;
}
.social-list.social-color li .fa.fa-google {
background: #dd4b39;
}
Hope it helps
