将鼠标悬停在CSS菜单活动的Li类上不起作用？ 对别人有用吗？

Question

我似乎无法使悬停按钮在我的第一个CSS菜单导航按钮上起作用。 这是一个活跃的li课，有人有什么想法吗？ 另一个菜单选项的悬停效果很好。 CSS代码：

@import url(http://fonts.googleapis.com/css?family=Open+Sans:600);
/* Menu CSS */#cssmenu,
#cssmenu > ul {
  background: url(images/highlight-bg.png) no-repeat;
  padding-bottom: 3px;
  font-family: 'Open Sans', sans-serif;
  font-weight: 600;
  left:0px;
  top:0px;  
}

#cssmenu:before,
#cssmenu:after,
#cssmenu > ul:before,
#cssmenu > ul:after {
  content: "";
  display: table;
}
#cssmenu:after,
#cssmenu > ul:after {
  clear: both;
}
#cssmenu {
  width: auto;
  zoom: 1;
}

li.space1{
    visibility: hidden;
}

li.space2{
    visibility: hidden;
}

#cssmenu > ul {
  background: url(images/menu-bg.png) no-repeat;
  margin: 0;
  padding: 0;
  position: relative;
}
#cssmenu > ul li {
  margin: 0;
  padding: 0;
  list-style: none;
}
#cssmenu > ul > li {
  float: left;
  position: relative;
}
#cssmenu > ul > li > a {
  padding: 20px 26px;
  display: block;
  color: white;
  font-size: 13px;
  text-decoration: none;
  text-transform: uppercase;
  text-shadow: 0 -1px 0 #9e3825;
  text-shadow: 0 -1px 0 rgba(116, 37, 2, 0.7);

  margin-right: 10px;

}
#cssmenu > ul > li:hover > a {
  background: url(images/hover.png) repeat;
  text-shadow: 0 -1px 0 #97321f;
  text-shadow: 0 -1px 0 rgba(122, 42, 26, 0.64);
}
#cssmenu > ul > li > a > span {
  line-height: 18px;
  margin-right: 5px;
}
#cssmenu > ul > li.active > a,
#cssmenu > ul > li > a:active {
  background: url(images/active.png) no-repeat;
}
/* Childs */
#cssmenu > ul ul {
  opacity: 0;

#cssmenu > ul li:hover ul {
  opacity: 1;
  visibility: visible;
  margin: 0;

  z-index: 2;
  top: 52px;
  left: 0;
}
#cssmenu > ul ul:before {

尝试这样： 演示

如果你需要鼠标的活动状态的效果，然后使用悬停主动li是这样的：

CSS：

#cssmenu > ul > li:hover > a,#cssmenu > ul > li:hover.active > a {
    background:#000 url(images/hover.png) repeat;
    text-shadow: 0 -1px 0 #97321f;
    text-shadow: 0 -1px 0 rgba(122, 42, 26, 0.64);
}
