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?

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。

#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 }

有一些技巧可以用于对齐元素。

01. 使用桌子戏法

.container { 显示:表; } .left { 背景:绿色; 显示:表格单元; 宽度:33.33大众; } .center { 背景:黄金; 显示:表格单元; 宽度:33.33大众; } 铃声{ 背景:灰色; 显示:表格单元; 宽度:33.33大众; } < div class = "容器" > < div class = "左" > 左 < / div > < div class = "中心" > 中心 < / div > < div class = "正确" > 正确的 < / div > < / div >

02. 使用弹性技巧

.container { 显示:flex; justify-content:中心; 对齐项目:中心; } .left { 背景:绿色; 宽度:33.33大众; } .center { 背景:黄金; 宽度:33.33大众; } 铃声{ 背景:灰色; 宽度:33.33大众; } < div class = "容器" > < div class = "左" > 左 < / div > < div class = "中心" > 中心 < / div > < div class = "正确" > 正确的 < / div > < / div >

03. 使用浮动把戏

.left { 背景:绿色; 宽度:100 px; 浮:左; } .center { 背景:黄金; 宽度:100 px; 浮:左; } 铃声{ 背景:灰色; 宽度:100 px; 浮:左; } < div class = "容器" > < div class = "左" > 左 < / div > < div class = "中心" > 中心 < / div > < div class = "正确" > 正确的 < / div > < / div >

.processList
  text-align: center
  li
  .leftProcess
    float: left
  .centerProcess
    float: none
    display: inline-block
  .rightProcess
    float: right

html
ul.processList.clearfix
  li.leftProcess

li.centerProcess
li.rightProcess

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; }
}

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。
