<style type="text/css">
.hotsearch dd{
float: left;
line-height: 24px;
margin-right: 30px;
overflow: hidden;
text-align: center;
width: 4em; /*这个值是看最长能显示几个文字，如x，则为x em*/
}
.hotsearch dd a{
display:block;
}
.w2{
letter-spacing:2em; /*如果需要y个字两端对齐，则为(x-y)/(y-1),这里是（4-2）/(2-1)=2em */
margin-right:-2em; /*同上*/
}
.w3{
letter-spacing:0.5em; /*如果需要y个字两端对齐，则为(x-y)/(y-1),这里是（4-3）/(3-1)=0.5em */
margin-right:-0.5em; /*同上*/
}
</style>
