Bootstrap导航栏（左侧菜单）在顶部未正确对齐

时间：2016-07-29 18:34:26

标签： javascript jquery html css twitter-bootstrap

左侧导航栏定位有问题。如果您在全屏幕上运行下面的剪辑并尝试调整浏览器大小，您会看到左侧导航栏未固定在页面顶部。

此外，标题（徽标和下拉菜单）不包括整页。

也许我错过了什么？

任何帮助都将受到高度赞赏！

谢谢，谁浪费时间查看这篇文章并帮助假人：）

答案 0 :(得分：0)

黑色导航栏的侧边栏类似乎打破了导航栏的功能。

PS：修复此问题会导致黑色导航栏固定在屏幕顶部并被白色导航栏覆盖，如果您希望黑色导航栏具有先例，则需要提升其z-index。
