    body {<!-- www  .j  a v  a 2 s.  co m-->
        font: 12px sans-serif;
        background: lightyellow;
    div#offset-four {
        background: yellow;
        border: 1px solid rgb(128, 128, 128);
        position: absolute;
        top: 20px;
        right: 20px;
        bottom: 20px;
        left: 20px;
    p {
        margin: 0;
        padding: 5px;
        border: 1px solid black;
    p#offset-y {
        position: absolute;
        top: 5px;
