我想有3个div对齐在一个容器div，就像这样:
[[LEFT] [CENTER] [RIGHT]]
容器div是100%宽(没有设定宽度)，中心div在调整容器大小后应该保持在中心。
所以我设置:
#container{width:100%;}
#left{float:left;width:100px;}
#right{float:right;width:100px;}
#center{margin:0 auto;width:100px;}
但它变成了:
[[LEFT] [CENTER] ]
[RIGHT]
任何建议吗?

你已经正确地做了，你只需要清除你的浮动。 简单的添加
overflow: auto;
到容器类。

HTML:
<div id="container" class="blog-pager">
<div id="left">Left</div>
<div id="right">Right</div>
<div id="center">Center</div>
</div>
CSS:
#container{width:98%; }
#left{float:left;}
#center{text-align:center;}
#right{float:right;}
text-align:中心;给予完美的中心对齐。

以下是当我用图像作为中心元素时，我必须对接受的答案做出的更改:
确保图像包含在div中(在本例中是#center)。如果不是，你将不得不设置显示为block，它似乎是相对于浮动元素之间的空间居中。 确保设置图像和它的容器的大小: #{中心 保证金:0自动; ｝ #center， #center > img { 宽度:100 px; 高度:汽车; ｝
CSS网格可以轻松完成工作:
#{容器 显示:网格;/*(1)一个网格容器*/ grid-auto-flow:列;/*(2)列布局*/ justify-content:之间的空间;/*(3)对齐列*/ 背景颜色:浅黄色; ｝ #容器> div { 宽度:100 px; 身高:100 px; 边框:2px红色虚线; ｝ < div id = "容器" > < div > < / div > < div > < / div > < div > < / div > < / div >
用twitter引导:
<p class="pull-left">Left aligned text.</p>
<p class="pull-right">Right aligned text.</p>
<p class="text-center">Center aligned text.</p>
我喜欢我的杠铃紧而有活力。这是css3和HTML 5
First, setting the Width to 100px is limiting. Don't do it. Second, setting the container's width to 100% will work ok, until were talking about it being a header/footer bar for the whole app, like a navigation or credits/copyright bar. Use right: 0; instead for that scenario. You are using id's (hash #container, #left, etc) instead of classes (.container, .left, etc), which is fine, unless you want to repeat your style pattern elsewhere in your code. I'd consider using classes instead. For HTML, no need to swap order for: left, center, & right. display: inline-block; fixes this, returning your code to something cleaner and logically in order again. Lastly, you need to clear the floats all up so that it doesn't mess with future <div>. You do this with the clear: both;
总结:
HTML:
<div class="container">
<div class="left"></div>
<div class="center"></div>
<div class="right"></div>
<div class="clear"></div>
</div>
CSS:
.container {right: 0; text-align: center;}
.container .left, .container .center, .container .right { display: inline-block; }
.container .left { float: left; }
.container .center { margin: 0 auto; }
.container .right { float: right; }
.clear { clear: both; }
如果使用HAML和SASS，则有加分项;)
HAML:
.container
.left
.center
.right
.clear
萨斯:
.container {
right: 0;
text-align: center;
.left, .center, .right { display: inline-block; }
.left { float: left; }
.center { margin: 0 auto; }
.right { float: right; }
.clear { clear: both; }
}
