nbsp;html PUBLIC "-//w3c//dtd html 4.0 transitional//en">
显示结果如下图：
我想要的结果是：
整个页面只显示一屏，
中间左右两栏要随浏览器自适应高度，因为 right 里边要加内容。
padding-top:130px;
*padding-top:133px!important;
padding-bottom:50px;
我设了这个高度，是因为#center的内容会顶上去，然后被header挡住。。不知道为什么。。。。
现在这个代码可以实现这步，各浏览器都有测试。
现在问题是，margin:0px auto;
这个在IE下不生效，页面不能居中 ，，，FF，GOOGLE浏览器都能居中。。
试过这个方法，在body里直接设，text-algin:center
因为我的实际页面有点复杂，结果后面所有的图片文字都居中了，我得一个个去调，太麻烦了。。。放弃。。。
然后在网上查到这个：
因为我最先声明的是
这个：“nbsp;html PUBLIC "-//w3c//dtd html 4.0 transitional//en">”
网上搜了一下，好像这个就会导致在IE中不能实现居中。
然后我把这下声明换成：
“nbsp;html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">”
就可以在IE下居中，其他浏览器也都可以。可是，左右两栏随浏览器自适应高度又出问题了。。。
如下图：
有点乱，，，求高手解。。。。怎么办啊。
回复讨论(解决方案)
用个JS多简单！
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title><style type="text/css">body{color:#000;margin:0;padding:0;}#main_container{ width:1000px; height:100%; display:block; margin:0 auto; padding:0; overflow:hidden; background-color:#066;}#header{ width:1000px; margin:0 auto; background-color:#09F; height:130px;}#center{ width:1000px;height:100%;overflow:auto; background-color:#993; }.left_content{ width:190px; float:left; height:100%; overflow: hidden; border-right:1px #005283 solid; background-color:#666;}#right_content{ width:809px; float:right; margin:0; height:100%; overflow:auto; background-color:#393;}.footer{ width:1000px; clear:both; height:50px; margin:0 auto;background-color:#F03;}</style></head><body><div id="main_container"> <div id="header"> header </div> <div id="center"> <div class="left_content"> left </div> <div id="right_content"> right </div> </div> <div class="footer"> footer </div></div><script>function $2(id){ return document.getElementById(id);}var winHeight = 0;function findDimensions(){if (window.innerHeight)winHeight = window.innerHeight;else if ((document.body) && (document.body.clientHeight))winHeight = document.body.clientHeight;if (document.documentElement && document.documentElement.clientHeight){ winHeight = document.documentElement.clientHeight;}var iframe = $2("center");iframe.style.height=winHeight-50-130+"px";}findDimensions();window.onresize=findDimensions;</script></body></html> 使用绝对定位也能实现自动适应高度。
用绝对定位。
谢谢三位。 解决了。
我也需要啊，该如何是好呢？
