在垂直下拉问题下使用渐变的CSS角度菜单

Question

我有一个有角度的菜单，下面有一个渐变，一直延续到上边缘。我还有一个subnav，它有一个不同的渐变，在主导航的渐变下面运行。一切看起来都是正确的，但是当您尝试翻转以从子菜单下拉菜单中进行选择时，它将不会让您转到主菜单上的下一个项目。我知道这是一个z索引问题，但我无法弄清楚如何使其外观和功能正常。

提前感谢你能解决这个问题的任何亮点!!!

我把它放在jsfiddle上：http://jsfiddle.net/jollyrogerd/EwFHY/3/

Answer 1

两种解决方案：

更好的一个：

JSFiddle

#cssmenu > ul > li.home:hover a,
#cssmenu > ul > li.productsrev:hover a,
#cssmenu > ul > li.about:hover a,
#cssmenu > ul > li.customers:hover a,
#cssmenu > ul > li.contact:hover a {
    z-index:501;
}
#cssmenu > ul > li.home > ul,
#cssmenu > ul > li.productsrev > ul,
#cssmenu > ul > li.about > ul,
#cssmenu > ul > li.customers > ul
#cssmenu > ul > li.contact > ul{
    z-index:500;
}

另一个：

JSFiddle

我将#cssmenu > ul，#cssmenu > ul li，#cssmenu > ul li a设为width: 90px;而不是width: 610px;

然后我添加了这两个：

#cssmenu > ul li ul li,
#cssmenu > ul li ul li a,
#cssmenu > ul >li:hover,
#cssmenu > ul >li:hover > a,
#cssmenu > ul >li > a:hover {
    width:610px;
}

在这里跟我说：我将subnav li和a设置为610px，并将顶级导航设为90px，除非它已悬停，然后将其设置为610px。

之前的问题是顶级导航与subnav重叠，因为它们都设置得太宽

但由于css-transformations，它将增长从90px增加到610px;

Answer 2

我通过在彩色渐变所在的位置使背景图形透明来修复它。所以看起来它落后了，但实际上是最重要的。谢谢你的帮助！

Answer 3

#cssmenu > ul li:not(:hover) {
    z-index: -101;
}

这使得所有未悬停的菜单项的z-index为-101。 这意味着当一个人被徘徊时，它不再具有-11的z-index使其高于子菜单，但是其他没有徘徊的其他人将仍然位于子菜单之下并且不能从那里盘旋。

它修复了问题，但看起来仍然很棒。

该菜单看起来很棒;）
