would you like something like this?
I add this class
#footer-container {
width: 100%;
display: inline-block;
text-align: center;
}
and made some changes in this class ( ex: remove the float )
.button-circle {
display: inline-block;
width: 66px;
height: 50px;
padding: 0px;
margin-top: 20px;
margin-right: 50px;
}
