How extend bootstrap classes

Question

I am doing my first steps with Bootstrap Twitter, and need to extend components. For example, I would like to change the navbar background, but without changing the original css file.

I tried to create a new class .test with the new background:

.test{
    background-color: red !important;
}

And I've invoked it in the hmtl as:

 <div class="navbar navbar-fixed-top test">

But, it doesn't work. How can do this?

Did my answer work? I see that you've asked another Bootstrap CSS override question: http://stackoverflow.com/questions/17355943/change-vertical-divider-navbar — Carol Skelly, Jun 28 '13 at 02:02

There are a few ways to customize/extend Bootstrap classes which are all discussed here: Twitter Bootstrap Customization Best Practices

If you intend to override the boostrap styles with your own custom CSS you should avoid using !important as this is generally a bad practice.

In the case of the navbar, the element that has the background-color is navbar-inner so you'd want to override like this:

.test .navbar-inner{
    background-color: red;
}
