Question

这是我的问题：https://jsfiddle.net/oa2b4cr9/

#nav{
max-width: 200px;
min-width: 200px;
float: left;
background-color: #CBDDE6;
border-right: 1px solid black;
padding-top: 15px;
}

#nav img{
    padding-bottom: 10px;
}

#pagecontent{
    border-left: 10px;
    max-width: 565px;
    min-width: 565px;
    float: right;
    padding-top: 10px;
    display: block;
}

我希望两个条形填充从页面顶部到底部的间隙。我在过去的几个小时里一直在研究，这让我有点生气！我试过了：将display：table添加到相关元素中将两列的最小/最大/高度设置为100％，并将容器推过页脚。添加清晰：在两个列下都有将溢出设置为隐藏将页脚的位置设置为相对而不是绝对。

如果有人可以提供帮助，我会非常感激。

Answer 1

在包含元素height上声明#content属性，例如：

#content{
  /* additional */
    height: 100%;
}

然后在嵌套的height元素上声明#nav属性，例如：

#nav{
  /* additional */
  height: 100%;
}

此外：

#footerbar元素已设置为position: fixed
padding-bottom已在#pagecontent元素上声明从正常文档中取出的页脚高度的帐户流量

如果您尝试根据浏览器视口定位元素，则不能很好地使用float或flex。你正在努力实现绝对的地位。

header{background:red; position:absolute; left:0; top:0; right:0; height:100px;}
nav{background:green; position:absolute; left:0; top:100px; bottom:50px; width:150px;}
content{background:yellow; position:absolute; left:150px; top:100px; right:0; bottom:50px;}
footer{background:blue; position:absolute; left:0; right:0; bottom:0; height:50px;}

<header></header>
<nav></nav>
<content></content>
<footer></footer>
