我的页面顶部有一个 133 像素高的标题栏。我将我的身体设置为位置：绝对和高度：100%。

我现在在下面还有两个 div 用于定位。我将它们设置为相对高度 100% 的位置，现在它从我的页面底部延伸了额外的 133 像素。如果我删除顶栏，高度是完美的 - 但顶栏将 100% 推到 100% + 133px。

也使顶栏成为绝对：

div#topbar {
    position: absolute;
    z-index: 1;
}

并为您的内容和侧边栏添加包装器 div，这些 div 具有顶部边缘：

<style>
    div.topbar-padding {
       margin-top: 133px;
    }
</style>    
<div id="body">
    <div id="sidebar">
        <div class="topbar-padding">
            &nbsp;afasdfadsfadf
        </div>
    </div>
    <div id="content">
      <div class="topbar-padding">
            &nbsp;afasdfadsfadf
        </div>
    </div>
  </div>

顶栏也应该是绝对的。

div#topbar {
    position:absolute;
    z-index:2;
}
