css floating footer margin

Question

i am trying to modify a sticky footer (http://www.cssstickyfooter.com/) to show a margin... it is easy for right and left with width:90% and margin:auto

#header {
    height: 33px;
    line-height: 33px;
    text-align: center;
    background-color: green;
}
html { height: 100%; }
body { height: 100%; width: 90%; margin: auto; }
#wrap { min-height: 100%; background-color:gray; }
#main {
    overflow: auto;
    padding-bottom: 33px; /* must be same height as the footer */
    background-color: red;
    height: 100%;
}
#footer {
    position: relative;
    margin-top: -33px; /* negative value of footer height */
    height: 33px;
    line-height: 33px;
    text-align: center;
    background-color:blue;
}
