.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

你可以试试这个:

你的html代码是这样的:

<div id="container">
  <div id="left"></div>
  <div id="right"></div>
  <div id="center"></div>
</div>

你的CSS代码是这样的:

#container{width:100%;}
#left{float:left;width:100px;}
#right{float:right;width:100px;}
#center{margin:0 auto;width:100px;}

所以，它的输出应该是这样的:

[[LEFT]       [CENTER]        [RIGHT]]

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%);
}

#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; }
}
