I am interested in updating the color scheme of a website that I modeled after this example: http://getbootstrap.com/examples/navbar/
So far, I have successfully changed the background color of the entire page using:
body{background-color:#XXXXXX}
However, I'm having difficulty modifying the background color of a specific div (which appears as grey on the linked page). I believe the div is part of a subclass named jumbotron, but I'm unsure. Although I can change the background color of elements within the div, such as paragraphs, I want to change the entire background of the div itself. Additionally, I would like to make similar changes to the navigation bar, which I think are related issues. Any guidance you could offer would be greatly appreciated!
