我是网络开发的新手。我试图让导航栏在页面上水平居中,尝试在这里查看其他类似的问题,但我仍然无法实现。提前谢谢。

我的CSS:

#mainNav{   
 background: #fff;
 height:40px;   

}

#mainNav li{
 float: left;
 list-style-type: none;
 z-index: 50;
 border-right: 1px solid #eee;
}

#mainNav li:last-child { border-right: 0; }

#mainNav ul a{
 display: block;
 text-decoration: none;
 padding-left: 28px;
 padding-right: 28px;
 padding-top: 15px;
 padding-bottom: 15px;
 font-size: 12px;
 color: #333333;
 font-weight: bold;
 text-transform: uppercase;
 height: inherit;
}

#mainNav ul ul a{
 line-height: 15px;
 font-weight: normal;
 border-top: none;  
}

我的HTML:

                <!-- BEGIN NAV WRAP --> 
            <div class="nav-wrap">



                <!-- BEGIN MAIN NAV FULL -->

我已回复here - 您可以inline-block添加ul

在你的css中更改这些

#mainNav{   
 background: #fff;
 height:40px;   
 text-align:center;
}
ul#menu-nav-menu{
 display: inline-block;
}
