I'm doing the one month rails class and in one of the lessons we're told to change some stuff from default to inverse. He doesn't go over why or whats the significance of it. If someone could explain to me that would be awesome.

Heres an example: nav class="navbar navbar-inverse" role="navigation" vs nav class="navbar navbar-default role="navigation"
推荐答案
样式类 (CSS) 负责配置元素的视觉外观.
Styling classes (CSS) are responsible for configuring the visual look and feel of the elements.
将 navbar-default 更改为 navbar-inverse 只会将导航栏的外观从明亮的调色板更改为深色.
Changing navbar-default to navbar-inverse simply changes the look of the navigation bar from bright to dark color palette.
