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。

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,在后面的代码在鼠标移到菜单上去就会向右浮动。代码如下:












test data 1 test data 1 test data 1 test data 1 test data 1 test data 1


test data 2



test data 3 test data 3 test data 3test data 3 test data 3 test data 3test data 3 test data 3 test data 3


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。

通过relative定位应该可以达到要求吧。

在上面代码的基础上,我改了一下。
