[英]CSS to fit sidebar under topbar
I need to create an empty topbar and an empty sidebar as below.我需要创建一个空的顶栏和一个空的侧边栏,如下所示。 I want to stack them neatly so that the top of the sidebar touches the bottom of the topbar.
我想将它们整齐地堆叠起来,以便侧边栏的顶部接触到顶栏的底部。 For that, I am using percentage.
为此,我使用百分比。 However, I just can't get them to do that.
但是,我就是不能让他们这样做。
I saw some other threads suggesting to set html
and body
with height: 100%;
我看到其他一些线程建议设置
html
和body
with height: 100%;
and width: 100%
.和
width: 100%
。 But in my app, the layout below is not in the main html document.但在我的应用程序中,下面的布局不在 html 主文档中。
#nav-bar { position: absolute; top: 0; left: 0; background-color: blue; height: 10%; width: 100%; } #side-bar { position: absolute; top: 0; left: 0; background-color: #011a21; height: 90%; width: 7.5%; /*margin-top: 10%;*/ }
<div id="nav-bar"> </div> <div id="side-bar"></div>
I tend to use flex box for this, Maybe grid would be smarter though.我倾向于为此使用弹性框,但也许网格会更聪明。 I took also care of some scrolling things.
我还处理了一些滚动的事情。 Using min with and height 0 on flex parents is key for that.
在弹性父母上使用 min 和 height 0 是关键。
body, section { min-height: 0; min-width: 0; } body { padding: 0; margin: 0; display: flex; flex-direction: column; height: 100vh; } nav { height: 2rem; background: green; } section { flex: 1 1 0%; display: flex; } aside { width: 4rem; background: blue; height: 100%; } main { background: pink; flex: 1 1 0%; overflow: auto; padding: 1rem; } div { border: 1px black dashed; height: 300%; }

Your #nav-bar
has a height: 10%
, and you can set the same value for the top
rule, selector #side-bar
.您的
#nav-bar
有一个height: 10%
,您可以为top
规则设置相同的值,选择器#side-bar
。
#nav-bar { position: absolute; top: 0; left: 0; background-color: blue; height: 10%; width: 100%; } #side-bar { position: absolute; top: 10%; left: 0; background-color: #011a21; height: 90%; width: 7.5%; /*margin-top: 10%;*/ }
<div id="nav-bar"> </div> <div id="side-bar"></div>
