css - 有菜单按钮居中的CSS下拉菜单

Question

我正在使用此 CSS 来设计我的菜单样式。菜单 li 当前设置为 float: left，这显然将它们定位在左侧，但我真的希望它们居中。

谁能帮我修改一下？

.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;
}
.menu ul{

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

}
.menu li{

    float:left;
    padding:0px;

    }
.menu li a{
    background:#6991B7 url("images/seperator.gif") bottom right no-repeat;
    color:#FFF;
    display:block;
    font-weight:normal;
    line-height:35px;
    margin:0px;
    padding:0px 25px;
    text-align:center;
    text-decoration:none;
    }
    .menu li a:hover, .menu ul li:hover a{
        background: #2580a2 url("images/hover.gif") bottom center no-repeat;
        color:#FFFFFF;
        text-decoration:none;
        }
.menu li ul{
    background:#333333;
    display:none;
    height:auto;
    padding:0px;
    margin:0px;
    border:0px;
    position:absolute;
    width:225px;
    z-index:200;
    /*top:1em;
    /*left:0;*/
    }
.menu li:hover ul{
    display:block;

    }
.menu li li {
    background:url('images/sub_sep.gif') bottom left no-repeat;
    display:block;
    float:none;
    margin:0px;
    padding:0px;
    width:225px;
    }
.menu li:hover li a{
    background:none;

    }
.menu li ul a{
    display:block;
    height:35px;
    font-size:12px;
    font-style:normal;
    margin:0px;
    padding:0px 10px 0px 15px;
    text-align:left;
    }
    .menu li ul a:hover, .menu li ul li:hover a{
        background:#2580a2 url('images/hover_sub.gif') center left no-repeat;
        border:0px;
        color:#ffffff;
        text-decoration:none;
        }
.menu p{
    clear:left;
    }

嘿，我想你想要你的 navi 显示中心检查这段代码，我在你的 css 代码中做了一些修改

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; 

CSS

    .menu{

border:none;
border:0px;
margin:0px auto;
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 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;
    display:inline-block;
    font-weight:normal;
    line-height:35px;
    margin:0px;
    padding:0px 25px;
    text-decoration:none;
    }
    .menu li a:hover, .menu ul li:hover a{
        background: #2580a2 url("images/hover.gif") bottom center no-repeat;
        color:#FFFFFF;
        text-decoration:none;
        }
.menu li ul{
    background:#333333;
    display:none;
    height:auto;
    padding:0px;
    margin:0px;
    border:0px;
    position:absolute;
    width:225px;
    z-index:200;
    /*top:1em;
    /*left:0;*/
    }
.menu li:hover ul{
    display:block;

    }
.menu li li {
    background:url('images/sub_sep.gif') bottom left no-repeat;
    display:block;
    float:none;
    margin:0px;
    padding:0px;
    width:225px;
    }
.menu li:hover li a{
    background:none;

    }
.menu li ul a{
    display:block;
    height:35px;
    font-size:12px;
    font-style:normal;
    margin:0px;
    padding:0px 10px 0px 15px;
    text-align:left;
    }
    .menu li ul a:hover, .menu li ul li:hover a{
        background:#2580a2 url('images/hover_sub.gif') center left no-repeat;
        border:0px;
        color:#ffffff;
        text-decoration:none;
        }
.menu p{
    clear:left;
    }   

HTML

<div class="menu">
<ul>
    <li><a href="#">Demo link</a></li>
    <li><a href="#">Demo link</a></li>
    <li><a href="#">Demo link</a></li>
