这是网站：http ://www.mccaonline.com

我被聘用处理网站上的渐变菜单问题。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，背景变为浅渐变绿色。然而，在 IE8 和 IE9 中，所有子菜单元素都分配有浅绿色渐变背景。

这是它在 IE8 中的外观

我只是希望它在 Internet Explorer 中具有相同的功能，并且无法弄清楚是什么导致它在所有子菜单元素上都具有渐变背景。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+ */

将此添加到您的 CSS 中。

#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。

取下过滤器标签并在 jquery 中处理菜单。它会影响菜单上的 2 个级别。
