Question

我正在创建一个垂直下拉菜单当您单击其中一个菜单项时。下拉列表将从宽度：0px变为宽度：500px; 由于某种原因，它不适用于FireFox和IE。在我开始之前，我在Jsfiddle.net上创建它，它适用于每个浏览器。

在jsfiddle制作的第一个菜单：

适用于Chrome - FireFox - IE - Safari和Opera http://jsfiddle.net/DennisBetman/3AyHK/

官方菜单粘贴在jsfiddle：

Answer 1

您添加了标记的链接。你的动画是基于li或ul获得焦点但现在链接得到了焦点....很快你删除链接并保持跨度（当然风格不再适用）它工作正常
