我的导航栏怎么是这样的
.nav{
height:40px;
}
.nav_left{
width:10px;
background:url(../images/images/nav_left.jpg)no-repeat;
float:left;
height:40px;
}
.nav_mid{
width:980px;
background:url(../images/images/nav_bg.jpg)repeat-x;
float:left;
}
.nav_right{
width:10px;
background:url(../images/images/nav_right.jpg)no-repeat;
float:left;
height:40px;
}
.nav_mid_left,.nav_mid_right{
float:left;
}
.nav_mid_left{
width:680px;
}
.nav_mid_right{
width:300px;
}
.nav_mid_left li{
float:left;
list-style-type:none;
width:100px;
text-align:center;
line-height:40px;
}
