radio buttons enabled

The trick is the label tag. It is createing the new radio buttons with a
pseudo class before.
Check RofWar_loginForm.css;
input[type=radio]:checked + label:before {
content: "\2022"; /* bullet symbol */
color: #f3f3f3;
font-size: 30px;
text-align: center;
line-height: 10px; /* position of radio bullet once selesecte */
}
