DIV等高布局，我想很多人都遇见过，我也看过不少的方法，有的是通过背景图片，实现假象的等高效果；
还有的用js实现等等。这些都是方法，但是现在都不用以上的方法，来个真正的纯css实现等高！

现在我们来看看真正的 CSS 实现的等高布局，其方法主要是采用“隐藏容器溢出”、“正内补丁”和“负外补丁”结合的方法实现的。下面来看看实际的例子（三列等高），以下面的 XHTML 代码为例：

<!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 http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>CSS等高布局</title> <style type="text/css"> *{ margin:0; padding:0; } #wrap{ overflow:hidden; width:1000px; margin:0 auto; } #left,#center,#right{ margin-bottom:-10000px; padding-bottom:10000px; } #left{ float:left; width:250px; background:#00FFFF; } #center{ float:left; width:500px; background:#FF0000; } #right{ float:right; width:250px; background:#00FF00; } </style> </head> <body> <div id="wrap"> <div id="left"> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> </div> <div id="center"> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> </div> <div id="right"> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> <a href="www.ietester.net" target="_blank">www.ietester.net</a> </div> </div> </body> </html>

提示：你可以先修改部分代码再运行。
