Question

以下是网站：http://www.mccaonline.com

我被雇用来处理网站上渐变菜单的问题。该菜单在Firefox，Chrome和Safari中正常运行 - 当您将鼠标悬停在菜单元素上时，背景将变为浅绿色渐变。但是，在IE8和IE9中，所有子菜单元素都分配了浅绿色渐变背景。

我只是希望它在Internet Explorer中的功能相同，并且无法弄清楚是什么导致它在所有子菜单元素上具有渐变背景。我用于导航的CSS如下：

#navigation {
    background: rgb(100,135,125); /* Old browsers */
    /* IE9 SVG, needs conditional override of 'filter' to 'none' */
    background: -moz-linear-gradient(top,  rgba(100,135,125,1) 0%, rgba(126,181,165,1) 50%,   rgba(126,181,165,1) 52%, rgba(143,190,174,1) 100%); /* FF3.6+ */
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(100,135,125,1)), color-stop(50%,rgba(126,181,165,1)), color-stop(52%,rgba(126,181,165,1)), color-stop(100%,rgba(143,190,174,1))); /* Chrome,Safari4+ */

让我知道您的想法或可能导致此问题的原因。我非常感谢任何帮助！

Answer 1

在你的CSS中添加它。

#navigation ul.nav .sub-menu li:hover , #navigation ul.nav .sub-menu li a:hover {background:none!important

你会得到你的解决方案。

Answer 2

您的样式不使用.sub-menu类，您是否尝试使用类删除背景：

.sub-menu .menu-item {
  background: ...

Answer 3

取下过滤器标签并在jquery中处理菜单。它会影响菜单上的2级。

IE8中的麻烦与菜单悬停元素上的背景渐变，在所有其他浏览器中工作
