Html IE9:锚定标记大小和li悬停问题
我正在尝试创建一个导航栏-使用常用的东西。它在Firefox和Chrome中可以正常工作,但在IE9中不能。显然有两个问题: 顶层的锚定标记不会填充包含的li。我 使用显示:块,高度:100%,宽度:100%,如您所见 在代码中。 顶级项目的悬停不会显示 较低级别的项目。悬停会更改字体和背景 虽然 关于这两个主题有很多文章和论坛帖子——我希望我已经理解并实施了讨论的解决方案。但也许我遗漏了一些简单的东西 css文件:dropdown-menu.cssHtml IE9:锚定标记大小和li悬停问题,html,css,navigation,internet-explorer-9,drop-down-menu,Html,Css,Navigation,Internet Explorer 9,Drop Down Menu,我正在尝试创建一个导航栏-使用常用的东西。它在Firefox和Chrome中可以正常工作,但在IE9中不能。显然有两个问题: 顶层的锚定标记不会填充包含的li。我 使用显示:块,高度:100%,宽度:100%,如您所见 在代码中。 顶级项目的悬停不会显示 较低级别的项目。悬停会更改字体和背景 虽然 关于这两个主题有很多文章和论坛帖子——我希望我已经理解并实施了讨论的解决方案。但也许我遗漏了一些简单的东西 css文件:dropdown-menu.css #navigation-ul { padd

Prajesh这篇文章的最后一行就成功了!以下是一些值得注意的观察结果,供将来可能面临类似问题的人参考 当然,IE过滤器梯度与ul不太匹配 或li-意思是如果梯度应用于li,则li得到 渐变,但其所有子项都隐藏或不显示在 将鼠标悬停在顶层li上。 但是,如果将过滤器应用于 li内部的元素,例如li内部的div, 然后渐变和下拉菜单都起作用。 在我的例子中,我想让我的顶级李在悬停时增加高度,并有次ul 顶部从顶部li结束的下方开始。因为过滤器没有安装 李一开始工作时,没有任何背景 因此,最高级别的li和次级别的ul之间存在差距。我 应该遵循默认公寓的最佳实践 背景,以防过滤器不工作。当我和你一起做的时候 过滤器注释掉了,下拉菜单运行良好,没有中断 在顶级li和次级ul之间。 我最初采纳的建议,结果是没有解决办法。在过滤器前面添加ms-or-ms或任何类似的东西本质上只是注释掉过滤器行。
在标记下添加这行代码 像这样

堆积如山的岩石!当我访问我的问题时,所有相关的线程都在右边。我查了这个:。讨论了用ms滤波器代替单纯的滤波器来实现梯度背景。它已经解决了这两个问题,但事实证明还有第三个问题隐藏在那里。悬停时,我希望顶部链接的高度变为150%,然后子菜单项开始。IE以正确的z索引启动子菜单,但不会增加顶部菜单项的高度。我刚刚注意到,添加了ms前缀后,渐变实际上消失了!
