Centering div with unknown width
提问by Linas
i have div <div id="container"></div>
which contains all page content including header footer etc.
我有<div id="container"></div>
包含所有页面内容的div ,包括页眉页脚等。
So i would like to center this div to the center of my page, now i have this css:
所以我想将这个 div 居中到我页面的中心,现在我有了这个 css:
#page{
position:relative;
margin:auto;
width:1000px;
}
And it works, but my problem is that content in this div keeps changing so the width changes too, it can be 1000px
or 10100px
so i need something like width:auto;
, how can do something like that?
它有效,但我的问题是这个 div 中的内容不断变化,因此宽度也发生变化,它可能是这样的,1000px
或者10100px
我需要类似的东西width:auto;
,如何做这样的事情?

One way is to create a wrapper around your #page
element, let's call it #wrapper
:
一种方法是围绕您的#page
元素创建一个包装器,我们称之为#wrapper
:
#wrapper {
position: relative;
left: 50%;
float: left;
}
#page {
position: relative;
left: -50%;
float: left;
}
This will allow the #page
div to remain a variable width.
这将允许#page
div 保持可变宽度。

This will give you a dinamically-sized div that stays at the center of the body and is the smallest size needed to fit the content:
这将为您提供一个尺寸大小的 div,该 div 位于主体的中心,并且是适合内容所需的最小尺寸:
body { text-align: center; }
div.container { display: inline-block; text-align: left; }

how about this?
这个怎么样?
body {
text-align: center;
}
#container {
text-align: left;
}
Assuming <body><div id="container"></div></body>
假设 <body><div id="container"></div></body>
