white-space:nowrap; + display:block 下面一种情况要注意
<style type="text/css">
html {
overflow: hidden;
}
body {
background: #222;

#menu {
padding: 10px;
background: #000;
height: 300px;
width: 400px;
}
#menu a {
display:block;
text-decoration:none;
font-family: arial, helvetica, verdana, sans-serif;
white-space: nowrap;
}
</style>
<script type="text/javascript"><!--
var P,T;
