The left, middle and right column layout of the page is relatively common in the current web page layout. Below I will share with you two good methods to achieve the left, middle and right column layout. The code is very detailed. Don’t miss it if you need it.

Copy and paste the following code to use:
Example 1:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta charset="gb2312" /> 
<style type="text/css"> 
.page_center { 
width:100%; 
} 
#nav { 
background-color:red; 
height:20px; 
} 
#left { 
width:120px; 
background-color:green; 
position:absolute; 
} 
#middle { 
background-color:yellow; 
} 
#right { 
width:120px; 
background-color:green; 
position:absolute; 
top:0; 
right:0; 
} 
#foot { 
background-color:pink; 
} 
#main { 
position:relative; 
} 
</style> 
</head> 
<body> 
<p id="nav" class="page_center">上边</p> 
<p id="main" class="page_center"> 
<p id="left">左边</p> 
<p id="middle"> 中间部分</p> 
<p id="right">右边</p> 
</p> 
<p id="foot" class="page_center">底边</p> 
</body> 
</html>
