覆盖IE中的CSS下拉菜单的YouTube视频内容9 [英] YouTube video content covering CSS drop down menus in IE < 9
问题描述
我使用CSS创建了下拉菜单,我在导航栏下方的一个框中放置了一个YouTube视频。使用IE 8时,下拉菜单会落在YouTube视频的后面,尽管导航栏的div的z-index高于YouTube视频的div。该问题在Firefox,Safari或IE9中不存在。
I've created drop down menus using CSS and I have a YouTube video placed in a box just below my nav bar. When using IE 8, the drop down menus fall behind the YouTube video, despite the fact that the div with the nav bar has a higher z-index than the div with the YouTube video. The problem does not exist in Firefox, Safari or IE9.
