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;
}

.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

使用CSS网格

layout { display: grid; grid-template-columns: repeat(3,1fr); } start-column { justify-self: start; } center-column { justify-self: center; } end-column { justify-self: end; } <layout> <start-column> <button>Start</button> </start-column> <center-column> <p>Center Donec non urna ipsum. Nullam euismod, lacus ac malesuada varius, mauris erat ullamcorper erat, eget dignissim tortor felis et sapien. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Morbi faucibus turpis et augue dapibus bibendum.</p> </center-column> <end-column> <a href="#">End</a> </end-column> </layout>

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>

如果左边、中间和右边的div有不同的宽度，你可以这样完成:

  #container {
    position: relative;
    width: 100%;
    text-align: center;
  }

  #left {
    position: absolute;
    left: 0px;
  }

  #right {
    position: absolute;
    right: 0px;
  }

  #center {
    display: inline-block;
  }

如果你的中心DIV是文本，你不需要#center CSS。
