        margin: 0;
        padding: 0;
    }
    html {
        height: auto;
    }
    body {
        margin: 0;
        padding: 0;
    }
    #container {
        background: #ffe3a6;
    }
    #wrapper {
        display: inline-block;
        border-left: 200px solid #d4c376;/*==此值等于左边栏的宽度值==*/
        position: relative;
        vertical-align: bottom;

    #sidebar {
        float: left;
        width: 200px;
