CSS
#left { background: #eee; width: 350px; height: 400px; float: left; } #right { background: #ccc; width: 150px; height: 400px; float: right; } #maincontainer { width: 500px; overflow: auto; } #foot { background: #eee; width: 500px; height: 100px; }
#foot{
clear:both
}
试试
*{margin:0;padding:0;}
LZ啥浏览器?
1楼和2楼的办法都可以试试
#foot { clear:both; background: #eee; width: 500px; height: 100px; }
测试了IE7、8、9、10和chrome,在IE7中出现这种现象,正在找解决方式。

需要加上
层来清除浮动~~<div id="maincontainer"><div id="left"></div><div id="right"></div><div class="clear"></div></div><div id="foot"></div>
.clear{clear:both;background: none;border: 0;display: block;float: none;font-size:0;margin:0;padding:0;overflow: hidden;visibility: hidden;width:0px;height:0px;line-height:0px;}#left { background: #eee; width: 350px; height: 400px; float: left; } #right { background: #ccc; width: 150px; height: 400px; float: right; } #maincontainer { width: 500px; overflow: auto; } #foot { background: #eee; width: 500px; height: 100px; }

大家误会了 我可能强调的也不对,这个是在VS2008的设计页面中的情况。浏览器运行是正常的。。。。
应该是上下div边距的问题
