以下是当我用图像作为中心元素时，我必须对接受的答案做出的更改:

确保图像包含在div中(在本例中是#center)。如果不是，你将不得不设置显示为block，它似乎是相对于浮动元素之间的空间居中。 确保设置图像和它的容器的大小: #{中心 保证金:0自动; ｝ #center， #center > img { 宽度:100 px; 高度:汽车; ｝

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。

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; }
}

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;
    }

你可以在JSFiddle现场看到它

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%);
}
