為什么我的li屬性的導(dǎo)航文本一開(kāi)始就不是在頂部，所以在設(shè)置line-height=40px時(shí)，文本就沒(méi)有在導(dǎo)航條中居中了，而是跑到導(dǎo)航條下面了呢？
.nav{height:40px;}
.nav_left{width:10px;
background:url(file:///C|/Users/Administrator/Documents/%E6%9C%AA%E5%91%BD%E5%90%8D%E7%AB%99%E7%82%B9%202/nav_left.jpg)no-repeat;}
.nav_mid{width:980px;background:url(file:///C|/Users/Administrator/Documents/%E6%9C%AA%E5%91%BD%E5%90%8D%E7%AB%99%E7%82%B9%202/nav_bg.jpg)repeat-x;}
.nav_right{width:10px;background:url(file:///C|/Users/Administrator/Documents/%E6%9C%AA%E5%91%BD%E5%90%8D%E7%AB%99%E7%82%B9%202/nav_right.jpg)no-repeat;height:40px;float:left;}
.nav_left,.nav_mid{height:40px;float:left;}
.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;}

是chrome嗎？記得添加
*{
? ? padding:0;
????margin:0;
}
ps:這個(gè)reset雖然有副作用，但是還是很好用的
