How can we expand the functionality of bootstrap classes?

As I navigate my first steps with Bootstrap Twitter, I find myself in need of extending components. Specifically, I am looking to customize the navbar background without altering the original css file.

My attempt involved creating a new class called .test with the desired background color:

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

I then applied this class in my html as follows:

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

However, it seems that my approach is not yielding the desired results. How can I achieve the customization I am looking for?

Answer №1

To enhance and personalize Bootstrap classes, there are multiple methods available which are thoroughly covered in this comprehensive guide: Best Practices for Tailoring Twitter Bootstrap

When attempting to replace the default Bootstrap styles with your own custom CSS, it is recommended to refrain from using !important as it is generally considered poor practice.

For customization of the navbar, make sure to target the navbar-inner element that controls the background-color property, as shown below:

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

Check out this example of a customized navbar:
