Question

当我调整浏览器窗口大小时，我从IE和Chrome中获得了一些意想不到的行为。导航菜单不会保持锁定状态。

我知道问题与标识正确对齐的长文本有关。在这种情况下，“漫画订阅...”文本。当此文本的“C”到达最后一个导航菜单项的边缘时，即导航菜单下降。

Answer 1

将position: absolute;添加到nav，将margin:45px auto;添加到#contents

Answer 2

问题似乎是<nav>没有清除浮动列表项。

将overflow:hidden;添加到您的<nav>元素，问题应该得到解决。 overflow:hidden;将强制容器扩展到其浮动子节点的高度。

IE和Chrome特定问题 - Firefox可以很好地显示导航
