我目前正在向网页添加导航栏。但我遇到了一些 CSS 样式问题。导航菜单栏正在推送下面的内容，中间留下了巨大的空隙，使其参差不齐。我采取了预防措施，省略了任何会弄乱底部的东西，margin bottom-padding但我仍然得到相同的结果。如何让菜单栏不影响下面的内容？例子

添加导航栏后： 在此处输入图像描述

没有导航栏，下面的内容是偶数： 在此处输入图像描述

我已将导致问题的特定 css 规则添加到devgrow.css：

<style>
#navigation {
    position:relative;
    top:-45px;
    left:450px;
}

#au_title {
    color: #FC821D;
    font-size: 120%;
    font-weight: bold;
    left: 515px;
    letter-spacing: 2px;
    position: relative;
    text-transform: uppercase;
    top: -105px;
}

#searchInput {
    left: 700px;
    position: relative;
    top: -180px;
}

#contentNav { color: #cfdae3; }

首先我要说编码真的很糟糕。为了解决该问题，请从您那里删除浮动button-list。像这样写：

.button-list {
    list-style: none outside none;
    overflow: hidden;
}

嘿，现在在你的 css id中定义 overflow hidden#contentArea

像这样

#contentArea {
    overflow: hidden;

}

在第一个内容区域的 css 中添加样式 clear

<div id="contentArea" style="clear:both">
