css浮动页脚边距

Question

我正在尝试修改粘性页脚（http://www.cssstickyfooter.com/）以显示边距...对于宽度：90％和边距：自动的左右来说很容易

，但是如何将高度达到90％（或显示某种顶部和底部边距）而不弄乱浮动页脚，

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;
}
