菜单按钮居中css下拉菜单

Question

我正在使用此css来设置我的菜单样式。菜单li的目前设置为float: left，显然它们位于左侧，但我真的很喜欢它们居中。

嘿，我想你想你的导航是展示中心检查这个代码，我在你的CSS代码中的一些修改

1. text-align:center put to .menu css 
2. .menu li, .menu li a define to display:inline-block; 
3. .menu ul define margin: 0 auto; and overflow:hidden;

    text-align:center; 
} 
.menu ul{ 

background:#6991B7; 
height:35px; 
list-style:none; 
margin:0 auto; 
padding:0; 
    overflow:hidden; 

} 
.menu li{ 

    display:inline-block; 
    padding:0px; 

    } 
.menu li a{ 
    background:#6991B7 url("images/seperator.gif") bottom right no-repeat; 
    color:#FFF;

尝试在.menu li a设置margin: 0 auto;。

你可以声明你的菜单li元素display:inline-block代替，然后使用text-align:center财产，像这样自动有你的菜单集装箱中心他们：

.menu{ 
    border:none; 
    border:0px; 
    margin:0px; 
    padding:0px; 
    font: 67.5% "Lucida Sans Unicode", "Bitstream Vera Sans", "Trebuchet Unicode MS", "Lucida Grande", Verdana, Helvetica, sans-serif; 
    font-size:14px; 
    font-weight:bold; 
    text-align:center; 
} 

.menu li{ 
    display:inline-block; 
    *display:inline; /* ie7 fix */ 
    padding:0px; 
}
