我现在用ul做了一个横向菜单，想把它放在“home”连接的右边，但我发现它运行时ul菜单始终会换行，是不是css出了问题，请大家给我指教一下，谢谢。建议用firefox浏览器运行。

回复讨论(解决方案)
在线等，请大家帮忙。
ul是块级元素，当然会换行，你可以强制它inline，其它自己调吧。
ul { display:inline}
把css的最后一行改成li:hover ul,.over ul { display:inline;}也不行，没办法只能用类似下面的坐标定位来调整了：
ul{
position:absolute;
top: 10px;
margin-left:100px;
}
<html xmlns="http://www.w3.org/1999/xhtml"><head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <title></title> <style> ul { padding:0; margin:0; list-style:none;display: inline;} li { float:left; width:140px; } ul li a { text-decoration:none; color:#777;} li:hover { background-color:#ddd;} ul li ul li table{ background-color:#ddd;} li ul { display:none;} li:hover ul,.over ul { display:block;} </style></head><body><div style="float: left;"> <a style="color:red;" > Home </a> | </div><ul style="float: left;"> <li><a href="">menu1</a> <ul> <li><a href="">test1</a></li> <li><a href="">test2</a></li> <li><a href="">test3</a></li> <li><a href="">test4</a></li> </ul> </li> <li><a href="javascript:void(0);">menu2</a> <ul> <li><a href="">test5</a></li> <li><a href="">test6</a></li> </ul> </li></ul></body></html> 这是在你写的基础上改的。
oNA_na:你的代码可以把位置调整，但也带来了新的问题，在929d1f5ca49e04fdcb27f9465b944689后面的代码在鼠标移到菜单上去就会向右浮动。代码如下：

这个定位问题很棘手也很急，我实在想不出来好的办法了，请大家帮忙。
我重新修改了一下css代码，定位正常了，但鼠标移到菜单上后面的元素就会往后移。

在上面代码的基础上，我改了一下。
