用到知识点:

float,块元素居中,注意:(如何让浮动元素和块元素在同一行--display: inline-block失效)

正确布局代码

<body>
  <div id="left"></div>
  <div id="right"></div>
  <div id="middle"></div>  
</body>

正确CSS

#left {
  height: 500px;
  width: 200px;
  border:2px solid red;
  float: left;
}

#middle {
  height: 500px;
  margin: 0 220px;
  border: 2px solid green;
}

#right {
  width: 200px;
  height: 500px;
  border:2px solid blue;
  float: right;
}
