its my first try to set up a footer on my webpage. I'm using fontawesome for displaying my git repo or certain other things.
For the git repo font I am using <i class="fa fa-github"></i>. In my CSS I want to create a circle around it with:
.fa-github{
    background-color: #333;
    color: #FFFFFF;
    border: 0.5rem solid #333;
    border-radius: 50%;
    font-size: 2rem; 
}
Can someone explain to me why i only get an oval shape instead of a circle ?
