What I love most about Bootstrap is its extensibility, and especially its decomposability. It's not widely appreciated that you can take subsets of Bootstrap, individual components for example, or its typography system, to use in non-Bootstrap scenarios. This is an acid test this project aces, easily. Bootstrap is the first place I look when I'm missing something in another project.
