我想添加与此代码相同的“社交按钮页脚”：（https://codepen.io/vpdemo/pen/WbMNJv），但是我的按钮不是圆形的，我该如何解决？
a, a:hover {
text-decoration: none;
}
.socialbtns, .socialbtns ul, .socialbtns li {
margin: 0;
padding: 5px;
}
.socialbtns li {
list-style: none outside none;
display: inline-block;
}
.socialbtns .fa {
color: #FFF;
background-color: #000;
width: 40px;
height: 28px;
padding-top: 12px;
border-radius: 20px;
-moz-border-radius: 20px;
-webkit-border-radius: 20px;
-o-border-radius: 20px;
transition: all ease 0.3s;
-moz-transition: all ease 0.3s;
-webkit-transition: all ease 0.3s;
-o-transition: all ease 0.3s;
transform: rotate(-360deg);
-moz-transform: rotate(-360deg);
-webkit-transform: rotate(-360deg);
-o-transform: rotate(-360deg);
}
.socialbtns .fa:hover {
transition: all ease 0.3s;
-moz-transition: all ease 0.3s;
-webkit-transition: all ease 0.3s;
-o-transition: all ease 0.3s;
transform: rotate(360deg);
