In this week's installment, Bart explains how to create two simple Bootstrap components, the Jumbotron and badges. A Jumbotron is a show-case area at the top of a website's front page that shouts out the site's main message and usually has a call to action. Badges are the little bubbles next to titles or within buttons that contain extra information. Often they contain a number, such as number of unread messages, or a short phrase like "New!" or "Best Value". It's a pretty easy lesson and the homework looks fun too as we figure out how to add badges to count the number of open alert windows and add a Jumbotron to our work.
