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?

使用CSS，像这样放置你的div(浮动优先):
<div id="container">
<div id="left"></div>
<div id="right"></div>
<div id="center"></div>
</div>
附注:你也可以向右浮动，然后向左浮动，然后向中心浮动。重要的是，浮动出现在“主”中心部分之前。
P.P.S.你经常想要最后在#容器里的这个片段:<div style="clear:both;></div>，它将垂直扩展#容器以包含两侧浮动，而不是仅从#中心取高度，并可能允许两侧突出底部。
#warpcontainer {width:800px; height:auto; border: 1px solid #000; float:left; }
#warpcontainer2 {width:260px; height:auto; border: 1px solid #000; float:left; clear:both; margin-top:10px }
我做了另一次尝试来简化它，并在不需要容器的情况下实现它。
HTML
<div class="box1">left side of the page</div>
<div class="box2">right side of the page</div>
<div class="box3">center of the page </div>
CSS
.box1 {
background-color: #ff0000;
width: 200px;
float: left;
}
.box2 {
background-color: #00ff00;
width: 200px;
float: right;
}
.box3 {
background-color: #0fffff;
width: 200px;
margin: 0 auto;
}

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; }
}
