Question

使用这个CSS代码，我怎样才能使它有一个活动/当前类？

#cssmenu *{
    z-index: 999
}
#cssmenu ul { margin: 0; padding: 0; text-align: center; }
#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 {
    display: inline-block;
    margin-left: 15px;
    position: relative;
}
#cssmenu > ul > li > a {
    color: #ffffff;
    font-size: 15px;
    line-height: 50px;
    padding: 16px 20px;
-webkit-transition: color .15s;
   -moz-transition: color .15s;
     -o-transition: color .15s;
        transition: color .15s;
}
#cssmenu > ul > li > a:hover {color: #ffffff; background-color:#666666; }
#cssmenu > ul > li > ul {
    opacity: 0;
    visibility: hidden;
    padding: 16px 0 20px 0;
    background-color: #eeeeee;
    text-align: left;
    position: absolute;
    top: 30px;
    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;

    visibility: visible;
}
#cssmenu > ul > li > ul:before{
    content: '';
    display: block;
    border-color: transparent transparent rgb(250,250,250) transparent;
    border-style: solid;
    border-width: 10px;
    position: absolute;
    top: -20px;
    left: 50%;
    margin-left: -10px;
}
#cssmenu > ul ul > li { position: relative;}
#cssmenu ul ul a{
    color: #000000;
    font-size: 13px;
    background-color: #eeeeee;
    padding: 5px 8px 7px 16px;
    display: block;
-webkit-transition: background-color .1s;
   -moz-transition: background-color .1s;
     -o-transition: background-color .1s;
        transition: background-color .1s;
}
#cssmenu ul ul a:hover {background-color: #f36f25;}
#cssmenu ul ul ul {
    visibility: hidden;
    opacity: 0;
    position: absolute;
    top: -16px;
    left: 206px;
    padding: 16px 0 20px 0;
    background-color: #eeeeee;
    text-align: left;
    width: 160px;

   -moz-box-shadow: 0px 1px 3px rgba(0,0,0,.4);
        box-shadow: 0px 1px 3px rgba(0,0,0,.4);
}
#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);
}

这里是完整菜单：http://jsfiddle.net/eza2Z/

此外，在子菜单上有一个向上的小箭头 - 如何将其颜色更改为与子菜单（#eeeeee）上的背景相同的颜色

还有一件事：）

当您将鼠标悬停在某个链接上并显示子菜单时，子菜单的顶部和底部会因其他原因显示其余部分后约1-2秒

非常感谢帮助：）

感谢

#cssmenu > ul > li.active {
  /* Add styles for currently "active" list items here */
}

如果您希望向下箭头与其父级具有相同的背景，则可以在background属性上使用继承规则，如下所示：

#myArrow {
  background-color: inherit; /* Will inherit from parent */
}
