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?

可能的答案，如果你想保持HTML的顺序而不使用flex。
HTML
<div class="a">
<div class="c">
the
</div>
<div class="c e">
jai ho
</div>
<div class="c d">
watsup
</div>
</div>
CSS
.a {
width: 500px;
margin: 0 auto;
border: 1px solid red;
position: relative;
display: table;
}
.c {
display: table-cell;
width:33%;
}
.d {
text-align: right;
}
.e {
position: absolute;
left: 50%;
display: inline;
width: auto;
transform: translateX(-50%);
}

最简单的解决方案是用3列组成一个表，并将该表居中。
html:
<div id="cont">
<table class="aa">
<tr>
<td>
<div id="left">
<h3 class="hh">Content1</h3>
</div>
</td>
<td>
<div id="center">
<h3 class="hh">Content2</h3>
</div>
</td>
<td>
<div id="right"><h3 class="hh">Content3</h3>
</div>
</td>
</tr>
</table>
</div>
css:
#cont
{
margin: 0px auto;
padding: 10px 10px;
}
#left
{
width: 200px;
height: 160px;
border: 5px solid #fff;
}
#center
{
width: 200px;
height: 160px;
border: 5px solid #fff;
}
#right
{
width: 200px;
height: 160px;
border: 5px solid #fff;
}
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; }
}
使用CSS3 Flexbox可以很容易地做到这一点，这个功能将在未来被几乎所有浏览器使用(当<IE9完全死亡时)。

HTML
<div class="container">
<div class="left">
Left
</div>
<div class="center">

<div class="right">

</div>
</div>
CSS
.container {
display: flex;
flex-flow: row nowrap; /* Align on the same line */
justify-content: space-between; /* Equal margin between the child elements */
}
Output: .container { display: flex; flex-flow: row nowrap; /* Align on the same line */ justify-content: space-between; /* Equal margin between the child elements */ } /* For Presentation, not needed */ .container > div { background: #5F85DB; padding: 5px; color: #fff; font-weight: bold; font-family: Tahoma; } <div class="container"> <div class="left"> Left </div> <div class="center"> Center </div> <div class="right"> Right </div> </div>
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 >
