我的导航菜单有这个CSS代码:
#cssmenu ul { margin: 0; padding: 0;}
#cssmenu li { margin: 0; padding: 0;}
#cssmenu a { margin: 0; padding: 0;}
#cssmenu ul {list-style: none;}
#cssmenu a {text-decoration: none;}
#cssmenu {height: 50px; background-color: #f36f25; box-shadow: 0px 2px 3px rgba(0,0,0,.4);}
#cssmenu > ul > li {
float: left;
margin-left: 15px;
position: relative;
}
#cssmenu > ul > li > a {
color: #ffffff;

}
#cssmenu > ul > li:hover > ul {

#cssmenu > ul > li > ul:before{

#cssmenu ul ul > li:hover > ul { opacity: 1; left: 196px; visibility: visible;}
#cssmenu ul ul a:hover{
background-color: #f36f25;
color: rgb(240,240,240);
}
我需要让子菜单框向上移动一点,这样你就可以在菜单的橙色部分(主位)上看到顶部的小箭头,并使其成为整页宽度,但是要建立链接/ text以页面为中心
这是一个小提琴:http://jsfiddle.net/dQnjt/
任何想法?

使用display: inline-block
代替float
并将text-align: center
添加到父ul
:
#cssmenu ul { margin: 0; padding: 0; text-align: center; }
#cssmenu > ul > li {
display: inline-block;
margin-left: 15px;
position: relative;
}
只需减少悬停时的最高值:
#cssmenu > ul > li:hover > ul {
opacity: 1;
top: 55px;
visibility: visible;
}

您只需添加ul:display:table; margin:0 auto;
,这会将浮动元素置于其中。

我添加了一个位置:相对于以下内容:
#cssmenu > ul > li > ul {
opacity: 0;
visibility: hidden;
padding: 16px 0 20px 0;
background-color: #eeeeee;
text-align: left;
position: relative;
left: 50%;
margin-left: -90px;
width: 180px;
-webkit-transition: all .3s .1s;
-moz-transition: all .3s .1s;
-o-transition: all .3s .1s;
transition: all .3s .1s;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
-webkit-box-shadow: 0px 1px 3px rgba(0,0,0,.4);
-moz-box-shadow: 0px 1px 3px rgba(0,0,0,.4);
box-shadow: 0px 1px 3px rgba(0,0,0,.4);
}
#cssmenu > ul > li:hover > ul {
opacity: 1;
top: 0px;
visibility: visible;
position:relative;
}
