Actually, this too works great.

input[type=submit]{
                 width: 15px;
                 position: absolute;
                 right: 20px;
                 bottom: 20px;
                 background: #09c;
                 color: #fff;
                 font-family: tahoma,geneva,algerian;
                 height: 30px;
                 -webkit-border-radius: 15px;
                 -moz-border-radius: 15px;
                 border-radius: 15px;
                 border: 1px solid #999;
             }
