<div class="container">
    <form role="form" style="width:400px; margin: 0 auto;">
        <h1>Registration Form</h1>

    vertical-align: middle;
    margin: -0.25em 0.25em 0em;
    background-color: #E8E8E8;
    border-color: #E8E8E8;

    top: 0em;
    right: 0em;
    z-index: 10;
    margin: 0em;
