Question

我目前正在试验Twitter Bootstrap，但我的固定侧边栏有问题。将鼠标悬停在左侧的菜单项上时，您可以看到菜单不会停止内容区域的开始位置。我真的不知道如何正确解释它，所以我希望这很清楚。

我想知道是否有解决方案。

Answer 1

将CSS替换为

 #sidebar .nav {
          width: 95%;
          position: fixed;
 }

以

#sidebar .nav { width: 10%; // change width as your choice position: fixed; }

您可以选择侧边栏95％的浏览器窗口宽度。
