以下是我的 CSS 代码。使用此代码，我将获得 100 像素宽度的左右菜单和 700 像素宽度的中间内容。（总宽度为 900px。）但是，我的要求是左右侧边栏宽度为 100px，中间内容宽度为 800px。（总宽度 1000px。）应该如何更改以下 CSS 代码来做到这一点？我尽力了，但是在更改值时它搞砸了。

html,
body {
    margin: 0;
    padding: 0;
    margin: 0 100px;
    background: url("assets/bg_paper.jpg") repeat-x;
}
body {
    font: 76% arial,sans-serif;
    text-align: center;
}
p { margin: 0 10px 10px }
a {
    display: block;
    color: #981793;
    padding: 10px;
}
div#header h1 {
    height: 80px;
    line-height: 80px;
    margin: 0;
    padding-left: 10px;
    background: #ffffff;
    color: #79B30B;
}
div#container { text-align: left }
div#content p { line-height: 1.4 }
div#navigation { background: #ffffff }
div#extra { background: #FFffff }
div#footer {
    background: #ffffff;
    color: #FFF;
}
div#footer p {
    margin: 0;
    padding: 5px 10px;
}
div#container {
    width: 900px;
    margin: 0 auto;
}
div#wrapper {
    float: left;
    width: 100%;
}
div#content { margin: 0 100px }
div#navigation {
    float: left;
    width: 100px;
    margin-left: -900px;
}
div#extra {
    float: left;
    width: 100px;
    margin-left: -100px;
}
div#footer {
    clear: left;
    width: 100%;
}

您也应该为此问题提供 HTML 代码。可能是您没有正确放置页面上的内容。因此，很容易判断您是否也在此处发布 HTML 文件。

试试这个

div#container {
width: 1000px;
margin: 0 auto;}
