我正在尝试布局一个页面,该页面在顶部和内容区域有一个水平导航栏,当内容太大时,它将获得滚动条.
我目前的做法是div宽度100%; 身高50px; 绝对的位置; 前0; 左0; 然后是第二个高度为100%的div; 宽度100%; margin-top 50px; 溢出:汽车; 但是,出现的滚动条会被50px的边距所抵消,因此会将内容从页面底部推出.如果我删除边距它一切正常但它将内容放在导航栏后面.
我也尝试将它包装在一个容器中进行试验,将边缘和溢出物放在孩子身上,但这似乎仍然没有达到要求的效果.
jsFiddle,有评论尝试更好地解释它.

<div id="nav">
<h1>Navigation</h1>
</div>
<!-- <div id="contentContainer"> -->
<div id="content">
<div id="oversizeContent">
<p>You can see the black border on this green box, but you cannot see the bottom black border. Similarly you cannot see the bottom arrow of the scrollbar.</p>
<p>I tried putting a wrapper around the content and putting the margin on that but the scrollbar still over flows Uncomment the contentContainer div and comment/uncomment the corresponding css.</p>
